Thank you for watching everyone, i love you all. This was a huge blow to me, to find out a lot of these various knives are failing. i dont believe that I have all the answers or that i have figured it all out. It is something I wanted to bring to light because we all work hard for our money and spend a lot of money on these knives. As a collector i have spent a lot of money on knives and to come to this conclusion is hurtful. Hopefully we can get this figured out as a community and continue to hold these companies responsible to give us the product we deserve. Dont forget to smash that Like button! Subscribe to the channel & let me know your thoughts and conclusions on this whole ordeal. -GBall

[@LostCoastEDC]

Pretty sure it’s the angle on the tang. Not enough flat where lockbar meets tang.

[@andrewlinn11]

Question for you...when did you buy the glass brigade frame lock?

[@levelonup0314]

⁠@@andrewlinn11I hate to shatter that impression, but I in fact have never bought or have even heard of Glass Brigade before now. But after some considering and puffs off my crack pipe, I am now stealing and trademarking the name Glass Brigade! Thanks for the awesome suggestion!

[@coryhessler2631]

Hey GBall just watched you whole video and this really sucks to see. That being said if you are interested in selling your Gripper or Relative get in contact with me

[@GBall_Vision]

It is geometry related for sure. Brass Brigade Gripper was bought when they came out or shortly after. Glass Brigade is 😎😂 I may consider selling the gripper, which is on my list to sell eventually anyways. The relative is #002 in Magnacut, I'm not selling that 😂 it's one of my babys either way

[@NeevesKnives]

its all about lock face geometry, the thinnest liner can take more load than the thickest framelock if the lockface geometry is off, thank you for this video i will be testing more, i used to doit every time but stopped, now i will doit more often, one thing you want to make sure is that your lockface is dry, oiled lockface can slip as theres less friction, to fix liners or frames you can scuff up the lockface with 300 grit sandpaper lightly and that can fix it but sometimes it needs a bit more

[@nicodiaz627]

Isnt a a framelock safer in everyday use when the knife is open? the hand naturally applies pressure to the lock bar making these issues almost non-important in an edc setting?

[@lionknives3]

​@@nicodiaz627that's a myth! The vibration is also a factor! For example if you check for Bladeplay and you press up and down and it's super strong, but than you spinewack it and it fails! And yes geometry is also one factor of it

[@nicodiaz627]

​@@lionknives3 Is it a myth that you apply pressure to the lock bar in a framelock knife? I doubt thats a myth its simple common sense. It might be false that liner locks are less safer than framelocks...

[@KanekiKen-lm1dl]

@@nicodiaz627definitely not a myth. It’s simple physics

[@austenhatch3285]

U have to make sure that your detent isn’t tuned too loose on frame locks and liner locks. On most of these that fail I bet if you just bent the lock bar in a bit it wouldn’t fail. Especially when u say that some pass and some fail of the same knife. That’s why. Same goes for button locks it all comes down to how the spring under the plunge is tuned

[@heyman1501]

Everybody involved in knives making knives, designing knives, and owning knives should be aware. Great video, Greg.

[@GBall_Vision]

Agreed 💯 thanks brother I appreciate it man 🤜🏻

[@wgkincheloe2458]

This shows how important lock-face geometry is. The thickest frame or liner can fail if the geometry is off just a little. I believe with button locks it's a little more to do with machining tolerances and making sure the button can't slip through the collar. Thank you for the video!

[@GBall_Vision]

You are on point I believe. I think the 2 most important things are lock geometry and blade geometry. It needs to stay locked up and it needs to cut well. Comfort is third. Action and all that are secondary really to the major things

[@5door]

Great work Greg. Old issue that is easily forgotten - almost always a design issue. Good to raise awareness periodically. Sucks on $300 knives, regardless of planned use

[@GBall_Vision]

Thanks brother I appreciate it man 🤜🏻💥

[@TheGerardo136]

The only thing we can do is consistently (as a community) test out all of our knives and hold manufacturers accountable 🤔

[@GBall_Vision]

I couldnt agree more. That is all I want, what is best for the knife community and what is best for the knives. Well said brother

@@christurnerct49 what Kizers? I wouldn't be scared. If you like a design and materials get it. The chance there's an issue is pretty slim

[@WhatsthePOINT_EDC]

Awesome video man! You’re right about everything. We shouldn’t have to worry if our knives are dangerous. I’ve been testing all my knives since my Benchmade Adamas 275 failed and cut me. I had to do a spine wack video to show people about a SOG. This is an important topic. Good stuff man.👊

Thanks brother I appreciate it and the info/input. 🤜🏻💥

[@mikecurtis2585]

I'm a Slip Joint guy! I just use every knife like it's a Slip Joint!

[@GBall_Vision]

That's not a bad idea brother. Thanks man

[@Jakoshdw]

I'm the same. I've been a user of knives as tools for roughly 30 something years since my childhood as a scout where my first real pocket knife was a slip joint. I could probably still count with my fingers how many times I've received an actual knife cut and only 1 was "serious". (As a teen I was sharpening a small chisel ground knife on one of those nail file tools from nail kit and my brother startled me. Cut straight to the bone and still have the scar on my thumb. Left me with serious respect for edged objects.) It just makes the most sense to me in practice to act as the knife could close on me at any time... and use the knife in a fashion that prevents it from doing so. This means not prying with my folding knives (carry a prybar for that) or stabbing with them (use a fixed blade if you absolutely have to stab and pry with a blade.) If I'm making a piercing cut with a folding knife... I usually have the blade in a pinch grip along the spine and use my thumb as a "depth stop".

[@KinKnives]

All my slip joints have lock failure😢

[@m.b.593]

I’m new to the whole knife thing, what’s a Slip Joint?

[@Jakoshdw]

@@m.b.593 - A slip joint is the spring mechanism that keeps the knife open or closed.The way the base of the blade at the joint and a back spring interact keep the knife open or closed... some of them are shaped to have a "half-stop" as well. It was used on the majority of older non locking traditional folding knives. Most Victorinox Swiss Army knives, Case knives, Great Eastern Cutlery, a large amount of traditional Buck knives... and the like are all slip joints.

[@Sludgecaked]

I'm glad to see the CJRB button locks are so reliable!

[@GBall_Vision]

They definitely do man! In my experience anyways, they all have passed and I own everyone of them until the mini Pyrite came out. Thanks brother

[@m4coyote]

Thank you sir! I will be testing all of my knives this way, and will dispose of the ones that fail. Even if they cost $500 - $600 or more, they aren't worth their weight if they will close on my hand !

[@GBall_Vision]

thanks brother! its an issue that needs fixed for sure - i will be thoroughly testing all the knives i have and will get. i have a lot of knives to test lol :(

[@brandnewamerican]

Dont think a knife is supposed to do that. Sucks to be so disappointed when spending so much coin. Gotta bring attention to it though so they can be held accountable or at least avoided.

[@GBall_Vision]

Agreed brother thanks man 🤜🏻💥

[@jakk9278]

Finally! Agreed! These test need to be done. Most of the popular knife reviewers never do it. All that money for these premium knives, looks and fidget factor isn’t everything.

[@GBall_Vision]

I will not be assuming anymore that is for sure, I will be testing every knife I own and any future knives I get. Thanks brother I appreciate it man

[@KinKnives]

It seem a lot of KZbin knife reviewers are salesman and don't want to talk too bad about a knife they are getting a commission on

[@GBall_Vision]

ive lost dealing with a few companies because of my honesty, i say that before anyone ever sends anything. im very open minded and can always find a use for even something cheap or what have you, but im going to be honest and do it in the kindest way possible. it is what it is brother!

[@bamaninja929]

To me a lock should stay locked no matter what I am doing with it! I'm a big, big fan of the Gripper and I'm shocked & sad that my favorite knife failed! Well, that's why you're my favorite channel, thanks brother Gbizzle no cap! 🙏🏾👊🏾💯

[@RWKnaf]

Unfortunately, regardless of how unlikely that motion might be in everyday use of our folding locking knives…. It is still a deal breaker. For me, anyway. Thanks for the video, bud! I’m sure this was as hard for you to shoot as it was for me to watch….

[@GBall_Vision]

Couldn't agree more man. Lots of companies produce knives that don't fail like this. It is definitely not something I want my knives to do. Regardless if it's unlikely, it's still possible. Thanks brother it was definitely tough to do. Got a lot more to do too sadly

[@levelonup0314]

I’m glad you’re bringing this to our attention! Only thing that I can think of that would change how that frame lock fails is during “normal” use your hand/fingers would be wrapped around the handle and helping hold in the frame lock. I know most frame locks are susceptible to death lock out when a small amount of pressure is applied on the lock bar when opening. Maybe a test where you apply a small amount of pressure(or even a varying degree of pressure) on the lock bar, it may not fail as badly as you might think. I think things like that need to be tested, within reason, which I think you tried your hardest to do and went about it in a fair and balanced way. It’s really interesting and I appreciate videos like this! Thanks G!

[@LAG3]

Cold Steel has been doing the tests you're talking about for years. I'm not a Lynn Thompson fan, but the tests are valid. Even the mighty Sebenza failed. I'm just trying to save you folks time and money. I've gone through every phase of collecting from slipjoint jack knives, the Boot and Rambo knife craze, butterfly knives, Spyderco/BM/Cold Steel, Customs. I've ended up with the Yojimbo with the Compression Lock as my EDC.

[@SaltMakerE]

@@LAG3 it's worth noting that the sebenza produced one of the worst results ever seen in cold steels testing, with even the kershaw leek proving to be stronger than the sebenza.

[@GBall_Vision]

LOP thanks brother. I am going to fully be testing out some of the various theories over the next days and weeks. One of which will be a standard grip and see what happens. Try and see what I come up with anyways. Thanks for the input and being here brother 🤜🏻

Lock geometry.. a problem that has been fixed a long time ago 😢😢😢

Right.. it burns me up for sure. I hope they go back to basics and get lock geometry blade geometry and the main ideals for knives down before action is concerned

[@THExDUDEx8624]

I was really surprised after a couple years with my Spartan Blades Pallas, I started having lock rock. No failure just lock rock. I tried fixing it multiple times. I was about to send it back to Spartan and decided to take another look. The spring inside the button was weak. I stretched it out and have had better lockup than with any other button locks. I'm sure it's going to wear out again and I might have to buy a stronger blade.

[@GBall_Vision]

Dude thanks for the info. I really appreciate it man. Glad your here brother 🤜🏻

[@a.k.9681]

Thank you. I just got a Spartan Pallas and the lock up fails. I can push it close from full open and lock position. With just the pressure of my thumb on the jimping. I am saddened. I had waited for so so long to finally get a Pallas. To only have it fail immediately.

[@SaidStevie]

I just checked my Gripper. It does the exact same thing. Slight tap on the spine of the blade and it disengages the lock. 🤔

[@GBall_Vision]

It's sad to experience. Especially with knives you love dearly. Thanks brother

[@onemooncollective]

That whole situation with those and that company is trash …🚮… never in my live have dealt with such shit from another maker and Iv been carry knives since I was a child and dealing with the other creators my hole life - Just bad business taking advantage of the community with someone right along shilling that bullshit and it just sad and disappointing some people aren’t who they are pretending to be and people are falling for it - Thats how I feel about it and I don’t think I’m too far off honestly -

[@attic42]

You are totally in the right to be alarmed. And all these companies should be put on blast and called out. Give us a detailed list (make and model) of each knife that fails. There's no excuse for an issue like this. Reviewers will point out blade centering issues left and right, and completely overlook this aspect (lock securty) which is far more important. As far as I'm concerned, you're doing the community a major service by highlighting this issue. Thank you. I really appreciate this video and your take on the whole matter.

[@BladeLabMiami]

It's not an issue for me because my use is pretty light duty, but I've been noticing this for a while. Some in my collection that will fail a modest spine whack: SBD Mini Tempest (Reate), GOM (Reate), ZT 0526, Kizer Original, Kunwu Zen, Varga VBR (Reate), Vosteed Racoon button lock, American Blade Works Model 2.... FWIW, my Voodoo passes, as does my Microtech Stitch ram lock. Demkos are good, McNees is good, Les George is good, AB is good, CJRB and Civivi button locks are good, all Spydercos are good, all Quiet Carries are good, and I have other Reate frame locks that are good as well.

Anyone who doesn't agree with you, and says that spine wack tests are stupid have no idea what a "locking" knife even means. I 100% agree with you that locks shouldn't fail with small spine wacks. These companies are wanting to get their product out so fast that their not even worried about correct lock geometry. It's actually really sad.

[@GBall_Vision]

Thank you brother I appreciate it man and I agree. Function has been taken over by form. So worried about action that blade and lock geometry get pushed to the side. The two things that really matter

[@chriss8206]

As far as the frame lock and the liner lock goes. it's a geometry issue if you have 2 square pieces of metal that are in alignment with each other it's strong. but when you push one at an angle to fraction of the edge that is actually touching the back of the blade where it's supposed to lock. it's a very minute piece of metal and when you're talking about titanium On a very hard steel is a very slippery surface.

[@GBall_Vision]

Agreed brother. It's a Geometry issue, production issue, quality control issue. If I was designing and producing a knife. I would make a proto first and make sure the blade geometry is right, the lock geometry is right and go down the list. It seems a lot is rushed nowadays and if it has good action its good to go

[@nicodiaz627]

My vosteed thunderbird and button lock racoon have these issues (as everyone knows already). I still use them and I have never had real world problems with them. Nonetheless, I think this critique is justified and acceptable.

[@joet81]

Have you noticed a correlation with the percentage of lockup you have on these liner and frame locks that are failing? I would imagine that it has something to do with the amount of surface area contacting and overlapping between the lock bar and the blade. Glad to know this info

Got to be honest, I made the assumption that frame and liner locks are much stronger than button locks and were not prone to fail. Good to know! Thanks!

[@GBall_Vision]

It's for sure an odd set of circumstances, definitely something to be aware of. Thanks brother

[@tacmechanic]

Imo I always assumed button/pluge locks were stronger than frame and liner locks, I have no fancy explanation other than the button 90 degrees to the blade, moving the force in a different direction...

[@GBall_Vision]

@@tacmechanic that's not a bad assumption to make really. In my testing experience - it's a high volume of button locks that fail, but with that said. I have some button locks that are built like tanks so they are capable of being very strong no question

[@ericblase4873]

Definitely a big issue. I have a feeling as a mechanical engineer those knives that fail an impact test would fail from a lower static load too. I especially want to test any of my knives with lock bar inserts. Thinking the inserts create a point for the blade to force the lock over compared to a full steel frame lock.

[@ericblase4873]

Just tested about 30 knives (all of my button locks and I think most frame/bolster locks) and my only two failures were Civivi Voltaic and Civivi Hypersonic. Two of the later ones I got to and it was surprising how easy they failed after 20 or so passed fine.

This should concern everyone. This is a hobby. You're spending money that you could be spending elsewhere on these. Doesn't matter if you only open mail, you should know if your knife's quality is crap.

[@KanekiKen-lm1dl]

But just because spine whacks can disengage your knife doesn’t mean that the knife itself is crap, and it absolutely matters what you use your knife for.

[@GBall_Vision]

Yeah technically not crap, just not properly finished id say. It's a blow but they're still usable, but this all goes back to companies designers and consumers picking form over function. We need to go back to function first and if great action comes with it then great thanks brothers 🤜🏻💥

[@tgonzalez1983]

I had a feeling these people whacking button locks were singling them out. Other locks should be tested just the same. The reason it cant be force closed is because your hand is holding the lock bar. I’m wondering if most youtubers won’t test them because they want to keep getting free products

[@GBall_Vision]

That's a very real possibility, very real. Idc I am going to be honest and transparent no matter the cost. I've already lost dealings with companies over not saying what they wanted or being honest. Which I told them I would be. That's one thing I'll always be on my channel is upfront and transparent 🤜🏻💥

[@Biomass1]

I believe it is the geometry of the mated surfaces of the lock faces. It's all about design. It doesn't really concern me much, however. I grew up with traditionals with no lock whatsoever and never cut myself with the blade closing. Never spine whack a folder. If i question lock strength then i grab a fixed blade.

[@GBall_Vision]

Definitely a geometry issue. I would say 9/,10 times it's a non issue as far as a hazard or injury. But still an issue at least to me, when I no they can be solid I've expected them all to be ya no. I get where your coming from as well. Definitely something to keep in mind though

Great video. As depressing as these kind of videos are to make, this is the most useful thing a reviewer can do. I'm going to have to check a few of my framelocks. As far back as three years ago, I was having issues with nearly ever Kizer I handled having lock up issues. Turned me off of them for awhile. This year I reviewed the Towser-K, a knife that had been hyped up so much to me. The lock up is not secure and I don't carry it. It's a shame. Keep up the good work!

Cold Steel has done all these tests. And as a CRK fan, I was saddened that even the mighty Sebenza failed. Their current Lock is still very similar to the good old fashioned Lock back. I did a test. I made myself carry a Spyderco Delica as my primary folder with my goal being a year. That ended up being about 3 years. I worked at Lowe's, a furniture store, then at Sam's Club. The Delica absorbed it all. I had no problems with the full flat grind. I am now carrying a Yojimbo 2 with the Compression Lock. I had a couple of them 5-6 years ago. When I saw the all blacked out version I had to give it another try. My fingers nor the meat of my hand comes anywhere near the lock. There's zero blade play. Once broken in it's been smooth to open. I accumulated 6 or 7 of them. I ended up finding the one I had with Brown G-10 and S90V for a reasonable price and couldn't be happier. I also have 2 Exclusives from DLT in 20CV. That Steel gets SO sharp. Literally shaving sharp.

[@GBall_Vision]

In today's world form has taken precedent over function and it's destroying things. If it looks good and has good action its pushed out the door. We need to go back to basics, lock geometry blade geometry is it comfortable will it hold up then worry about multiple deployments and action once the main ideas of the knife are taken care of. Just my 2 cents

[@Josh-jw7cb]

This is exactly the point of a framelock there has been much written about how worthless this test is for framelocks. Button locks failing would be the most concerning.

[@marklex414]

I don't want to make up for a manufacturer's lack of quality control and due diligence. These knives aren't sold as slip joints. It doesn't matter what angle the pressure or shock comes from they should stay locked within a reasonable margin or the industry should stop using that lock type. My brother-in-law is a fan of car racing. He has educated me on their improvements in safety. They didn't say, "Well don't run into the wall!" They said how can we make the car and helmet safer in case a crash happens. I don't want to have to disassemble every knife I get and dry off the lock face or take sandpaper to the lock face. They have engineers. How can they possibly not understand lock face geometry and not account for it in the design? Are knife manufacturers really listening to the community? I have only been watching knife reviews for 6 months and every reviewer complains about the continued use of T6 screws, the failure to create a proper choil, and the lack of jimping. Did the knife manufacturers buy millions of T6 screws in the 70's and just haven't run out of them yet? Lol!

[@GBall_Vision]

Agreed 💯💯. I'm hoping things change for the better for sure. On a lot of different accounts. Things are getting better for sure, still lots to get right though for sure

[@richardcasner7665]

This is very concerning. The one good thing about a frame lock is that your hand acts as a secondary lock, not allowing the Lockhart to move as long as you are griping it. When you turn it over and tap the spine, you're not holding the lock bar in place. Either way, it's pretty concerning.

[@GBall_Vision]

Agreed on all accounts, I hope they get it figured out. Get on the same page as the models that are solid 🤜🏻💥

[@Edgekeeper747]

Thank you for making this video. I ALWAYS make sure either knife is strong lock wise or there’s a large long finger choil in case it does close when I buy knives. This way you don’t get injured. Or it’s not gonna send me to the hospital if it does. Great vid. More knife guys and gals need to look at this. It’s a big issue to me. Thanks again

[@Edgekeeper747]

Also if I’m paying $65+ for a knife it should be strong and not fail these light spine whacks period

[@CastIronPrimate]

​@@Edgekeeper747I don't think price should come in to it dude, any knife that risky should never have made it to retail.

[@budthecyborg4575]

"your hand acts as a secondary lock" No it doesn't, the pressure from your squishy hand is nothing compared to the forces pushing the lock out. The only way this would be remotely true is if the lockbar has a big "saddle" mounted on top of it for the pad of your finger to apply pressure over a larger surface area.

[@GuyMoulton]

Last year, when this frame lock failure story started to break, I tested all my knives no matter the lock. I had a Sativien with a crossbar lock that failed ($25 out the window). It was on bearings and a great knife EXCEPT it failed the spine thwack test. I had a Kershaw-Emerson CQC-4KXL D2 (one of my faves!) with a frame lock that failed too. I don't use knives that might fold. I cut a lot of heavy cardboard carpet tubes. I will put a lot of pressure on the knife in the wrong way getting the knife out of the tube when I reset the knife position halfway. I don't trust frame locks anymore or cheap Chinese knives either. I have a CJRB Chord button lock- tha was dead solid no matter how much I thwacked it. I'm not crazy about the steel but it has nice action and won't fail the spine thwack

[@GBall_Vision]

Yeah I started a war without knowing it 😂 but I think companies started to get things figured out. I have through testing figured or some of the failures were either due to coated liners/blades or both, oil on lock face or debris. It's not a bad idea to take them apart and sand the lock face a little bit And the Tang then clean them up and see what happens. I fixed three like that

[@TeeFetch]

Class Action heh

[@GBall_Vision]

😂

[@RichardTaylor-m8l]

Is it like maybe an impact generated bounce of the lock bar ? Like it’s springing loose for a better word ?

[@GBall_Vision]

There's a lot to digest with it all and could be a few various things. Typically this means the geometry of the lockbars face or the tang is off. Could be from oil could be from debris. It could be force but I don't believe so. As I demonstrate there's titanium frame lock knives that hold up just fine. I'm going to be testing several hundred knives and maybe have a better idea on it thanks brother

@@GBall_Vision You know I’ve done this years ago and was why I never liked liner locks , but I really never thought a premium or newer up to date knife would have these problems, This is great that you reintroduced this as a possible problem , I was cringing when I was blasting my TFF-1 hoping it wasn’t gonna fail 😂, Maybe lock stick might be a good thing after all

[@keepitsharp-x4s]

this might be the obvious answer , but i cant think of any other reason. its the vibration caused by the spinewhak and how it reverberates thru the material of the knife. or its the shape, or the geometry of the mechanism. whats crazy is that these companies arent checking the locks!! wtf is going on here! this is insane!! awesome video! thanks for your concern.....

[@GBall_Vision]

Àround 4-5 years ago I remember a few companies would test the locks by doing a light spine whack test, I think over the course of time and the "drop shut" action and all of this, they stopped testing them. I believe it's a geometry issue, when they are failing due to the lightest of taps, it's geometry. Thanks for being here brother 🤜🏻

[@jreviews5924]

Waiting for the couch commandos to come in and say “you don’t spine wack a knife!” Lol. No knife should fail this test. If you stab into something those knives that failed will cut you bad.

💪🏻🙏🏻🤜🏻💥 dude it's "vibration" lmao 🤣 I agree man. I have knives I can smash in to a 2x and they laugh. When a knife folds up because of a light tap, there's an issue. Especially if you plan on using the fcker, that's the thing. Alot of people don't use them, they flick it all day, they just choose form over function. I'm a carpenter and have been one for over 15 years now, I get to use and test a lot of knives when I want on whatever I want. It's getting out of hand. We need to go back to basics and get blade and lock geometry right then if it's fidgety then fine but this shit is killing me 😂 thanks brother 🙏🏻🤜🏻

Thank you for bringing this to everyone's attention. I'll have to think about everything you asked about. Really dont know at this point. What I do know is I have about 40 knife spines to whack against a board. Mostly liner/frame locks, a few button locks, and even fewer crossbars. Pretty much all made within the last few years. Mostly budget, couple $200 guys in the mix though.You interested in a pass/fail list or anything if I get around to it?

[@KandKo]

It's crazy... The poster child for this issue is zero tolerance. Love the designs but only one of them I had was solid and didn't fail (the emerson design). Sold them all. Fast forward several years, the 0545 comes out. Awesome looking knife, super light, pretty much ideal. And being they have to be aware of all the lock failure videos out there I figured there was zero possibility they hadn't fixed it with a bran new knife design. I was wrong. 1-3 light taps like are done in this video and fail. Insane that they haven't fixed that issue yet. Perhaps they should just ditch frame locks all together because apparently they just can't get it right.

[@GBall_Vision]

They really are, it stems back at minimum 3-4 years easy, and they've always had issues. I don't get it. It's definitely a known problem. The geometry should be so simple to figure out at this point but not the case for some. Some nail it, with early lock up and some can't do it at all

[@tonyboombotz]

great video bro. I've been going through this for a while. I had one on lifting from what I was cutting that failed and cut across 3 fingers, yes, a fking issue. but the manufacture which is small USA co. who I contacted fixed the problem. asap and even upgraded the blade from 20cv (which I actually loved) to magnacut. but if an inexpensive knife holds. well, a high dollar knife better perform to perfection. I also seem to find a difference with lock bar angle. but like you I'm still testing. surprisingly button locks seem fairly strong. which I didn't expect.

[@GBall_Vision]

Nah man that' never happens, to anyone, EVER!! It's not logical, it's not possible!! At least according to some people here in the comments 🤣 on a real note, we have a lot to learn and find out.

[@SaltMakerE]

Fantastic video. Want a real shock and awe test? Try smacking a Sebenza 21. Despite being one of the most highly praised knives in the world, described as bank vault lockup, it's lock is incredibly feeble and weak with the lock face slipping under even the lightest pressure. Testing from Sal Glesser showed its weakness, as well as Cold Steel's testing (where it spectacularly failed and produced one of the worst results ever). Of course, what you will find doing these types of tests is that the only thing stronger than the locks themselves will be the strawman arguments and emotional responses from the fanboys when their particular choice of knife does not do well in your testing.

[@GBall_Vision]

"the test is not valid" 😂 well it is when there's tons of knives passing... And the people who know me, know that I'm an EMPEDC fan boy, which is why I tested them and showed one failing, same for null knives. Just to show I wasn't being a dick. I care about the people in the community and the stuff we buy and I think secrets can destroy a community or people in it. Thanks for being here brother 🤜🏻💥

[@charlesard8639]

It's also the shaking from tapping. If you just were to put constant pressure, it probably would not fail.

[@GBall_Vision]

That is something I discuss later in the video brother. But that is correct so far, applying pressure that way, i have not been able to get them to fail. none the less though, buying a locking knife, it should stay locked up. It can be done, other companies/knives hold up completely fine, in my opinion there is no excuse for it man

[@RWKnaf]

Hey bud. I had a thought. How new are the premium folders you tested? How many times have they been opened? I was thinking about my Giantmouse Biblio, it’s a liner lock. When I first got it the lock up was suuuper early. In fact, I’m still breaking it and it’s been almost a year. But at first it would fail, if spinewacked. Now it doesn’t. This maybe a dumb question, but the knives that are failing. How early is the lock up? I wonder if that has anything to do with it. Also, I saw a spinewack test on another coated Gripper, and it passed. Maybe coating the blade/lock face, would prevent failure. Maybe a light spritz of a durable clear topcoat of would fix it?

[@GBall_Vision]

Im going to try and do some different things concerning the knives, cleaning, coating with some graphite maybe. See what happens. Most of those are pretty new with not a ton of opening and closing. All from this year. Definitely a lot to diagnose man. Thanks for the info brother 🤜🏻💥

[@BrandonGavin_EDC]

Seems like the Gripper needs to change the lock face geometry on the V2 or V3 or whatever it’s on. As other have said at least on a frame lock your grip makes the lock stronger. That is way too easy to fail though. I’d send that in for warranty.

[@GBall_Vision]

Agreed Brandon, I want to check all of them and then I'll decide what to do. Thanks brother 🙏🏻🙏🏻🙏🏻

[@ashleyempie1418]

[@M1911jln]

You are mistaking force with impact -- they are two different things. I suspect if you just apply force to the blade on your "failing" knives that they lock won't fail. Do you regularly smack the top of your blade? I don't think that is a likely scenario in actual use.

[@GBall_Vision]

I don't use the best terms that I should have in some parts of the video, but I do explain near the middle to the end of the video. The difference between both the impact and force ideal. nonetheless, many companies have proven that they can make a folding locking knife design and build That stays locked up under such a rudimentary test, there is a difference between the two tests. It does happen in a cut if you were to come back up out of the cut in to the material, I've talked with quite a few people who this has happened to. I haven't personally had a knife close on my hand but I have been in instances where I'm cutting and forcefully bring the knife back up out of the cut in to material it just hasn't failed on me And that's the idea behind this, it's a rare occurrence but it's an issue that needs addressed. Locking knives should remain locked up Thanks for watching brother

[@giantfatberg]

People are tiring of this comment about this issue. When your favorite knife folds with a little whack it makes you sick. Especially if you paid $400 for it

[@t8858x]

Yep. Every folding knife that fails the most basic safety tests should be RECALLED. Looking fancy isn't the most important thing. These are BLADES. Knife reviewers are too focused on commissions and what *looks* coolest, or what's newest, which is damaging to the community. That's why the honest and thorough reviewers are so valuable.

i'd be interested in understanding the actual physics behind this and how the lock face interacts with the blade stop(especially on frame or liner locks)...it doesn't make sense that it would do the exact opposite of what your brain is telling you it would do, and yet...it does exactly that lol...

[@dirkpinkerton9295]

Pretty much all locks can fail. Thickness of material helps resist lock failue or release. Lock geometry is of primary importance. If that is correct for any lock, failure, slippage or release is less likely. The spine whack test is a good test, but not the end all test. If you do a spine whack and get the correct resonance/vibration between blade and lock this will cause the lock to release. It isn't the lock so much failing as physics doing its thing. This is one reason why spine whack test isn't the definitive test. Button locks require very tight tloerances to not fail. But if tolerance are that tight, it isn't easy to operate. That is why a button lock knife shouldn't be a hard use knife. Crossbar locks are a good system but still require correct geometry. they can also be subject to resonance but less likely. Back locks, done properly are excellent. Few get them right.

[@GBall_Vision]

Thanks for the insight And info Dirk. One thing that I don't understand is I have knives that have very tight tolerances and do not fail their lock up, but they are also very smooth and easy to open as well as easy to move the lock bar and disengage. Disengaging the lock and then the other thing that I don't understand is as far as vibration and that sort of thing. Why can I take two frame locks from the same manufacturer and one will fail due to a very light tap and another one I can smash like I'm swinging a baseball bat and it doesn't close but with equally good opening action, closing action and disengagement. Of course, I understand quality control issues and knives slipping through the cracks, but I don't believe knives should fail their lockup due to such a lightweight test on their spine. Especially when lots of knives with the same locking mechanisms pass the same exact test

[@GBall_Vision]

Dirk btw I love a lot of your designs brother. I have several of them. Keep up the good work my man

[@dirkpinkerton9295]

@tacticalcenter8658 That is unfortunate. However, if everyone liked the same stuff, life would be quite boring.

[@dirkpinkerton9295]

@GBall_Vision I am with you. Folders shouldn't fail. We can make a long list of why they fail. For manufacturers, I think the big thing nowadays is QC. That isn't just for the lock geometry of a folder but also how everything else is fitting together. Also materials, are they getting consistent heat treat, are they maintaining their tooling, or do they use it a bit longer to save a few bucks. As for your knives with tight tolerances, that function well and don't fail. That is the result of proper design, skilled machining, and attention to detail. Doing these things right take time and cost money. That is why you don't see this as an industry standard.

[@curtishatridge4325]

After watching the fails demonstrated in your video, I felt compelled to test the 4 knives I have with me using the same spine test you used. I didn't have a 2X4 handy, so I just used the edge of my desk. the 4 knives tested were (1) GiantMouse Ace Biblio frame lock (2) Mikkel Willumsen Chibs liner lock #'2 3 & 4 are both new from CJRB and are (3) Mica button lock & (4) Resource liner lock. None of the 4 failed the test, although the GiantMouse looked to be close to failing. After examining it carefully, I see that it has the least positive lock up of the 4, with barely 1/16" lock/blade match up. Even with these positive tests I feel it necessary to test each of my knives as I carry them. I have LOTS of knives, and keep many of them in my EDC rotation. Thanks for the heads up, safety definitely comes first!

[@LAG3]

I have the Resource, a Big Banter, and Artisan Snody Xcelerator. All 3 lock up solid as a brick with no blade play and still smooth to open. I'm impressed they can mass produce this kind of quality at the prices they sell for. I am a fan of steel liner locks. They hardly wear at all unlike some Ti linerlocks I've owned. I had several of the number one hard use knives in the world where the Ti liner wore across the steel blade in a few months. I just won't spend money on a maybe. Especially a quite expensive maybe.

[@curtishatridge4325]

Had to relate the test from my newly acquired Bestech Fairchild, a knife that is in the $325 neighborhood. Testing in the same manner as the above described (and shown) tests, the Fairchild failed when struck near the tip virtually every single time. It held up much better when the strike was made nearer the pivot. This is a frame lock knife, and I discovered that if I manually push the lock bar in an effort to secure the lock up it does not fail the test. I did not notice any visual difference in the lock up, but I'm old and don't see as well as I used to. In neither scenario did I strike with a great deal of force. I honestly don't know how many folders I have, probably somewhere between 300 & 500. I've got a lot of testing to do...

[@lando8913]

Look at the lock face. Its angled in such a way that downward force would push the lock bar out. And its only half or less under the blade. The ones that aren't failing appear to have a flatter contact area, and/or the lock passes the halfway point of the blade stock. Even if its just 51%. Just my guess from what I'm able to see in the video. I don't know about button locks. Edit: Wrote before you explained the same thing. Oops.

For most expensive knife buyers, use them for expensive paperweights and bragging. So many never go through any paces if used at all. Shock to the back of the blade will make easy rather than stiff close Frame locks will vibrate open in all metal frames. Geometry can be to blame especially with the smooth ease closing is a good recipe for disaster, but that's why we have choice. Probably why coldsteel never really explored Frame locks...

On liner/frame locks, the farthest from the pivot is the point of contact, the best it is and the angle in the blade part should not be too low.

😂 herrreeeee We, GOOO In my best joker voice

Very few folders can hold up to heavy use. Not what they are made for. But that is ridiculous

[@GBall_Vision]

Definitely not comparable to a fixed blade but They should be able to withstand some light heavy use there not slip joints ya no If they manufactured the proper geometry it would be locked up nice and tight. And it can also maintain smooth action and easy disengagement but I think that takes a lot more attention to detail Thanks brother 🤜🏻💥

[@Nordraw]

@@GBall_Vision yeah it’s pretty bad they failed that simple test

Thanks for being here brother I appreciate it man 🤜🏻💥

What exactly isn’t scientific about this? You made an observation, carefully considered what it meant, came up with a test, you recognized your own bias and margin of error, especially given the sample size. You also gave an excellent example of how this can reasonably happen to anyone. This is all logically reasonable and scientific. I think what’s probably happened is knife makers have made the same assumptions enthusiasts have, liner/frame locks are tough and safe while newer designs like button locks may not have been designed with durability or safety in mind, so they don’t test the locks that they believe to be of sound design and end up with failures while they are doing more testing on things like a button lock and so we’re seeing less failures with them. That’s obviously not 100% the case but I believe it’s probably true to some extent. I personally wouldn’t hold something like this against a company as long as they addressed it going forward. Now should they try to address the issue with knives that are sold and in circulation already, I think so but I could understand the hardship and costs associated with that. I know for me I don’t use my knives extremely hard but I do use them as they were intended to be so this is a serious concern to me, I can see a few scenarios in which an accidental closing could happen and result in a serious injury. Manufactures should be very careful now that this has been brought to the publics attention.

Thank You man, I say a lot of those things just to cover myself against the people who would defend something like this happening. I appreciate your observations of the video and what I said. My way of showing not being as biased as possible was testing one of my favorite knives and companies in EMPEDC /Relative. Any knife that fails simply is a huge downer. Nobody should be attacked but it needs to be corrected over time in my opinion. Whether the person needs it or not it should still be proper. I've heard a lot of stories of guys who didn't really use knives hard then they went to cut down something fairly substantial and the lock failed on them in one way or another. Thanks for watching and the comment man 🤜🏻💥

Keep em honest G!

[@GBall_Vision]

Thanks brother, I just hope we can get the issue figured out

[@ericfisher1311]

new zt 545 spine whack will fail, light use knife though

[@GBall_Vision]

Thanks brother I appreciate it. Good info man

My thoughts on specifically WHY this knife fails with a light tap are going to be from the experience of a guy that works on a lot of chinese oem produced knives. It could be 2 things, either the lock insert was not ground quite enough and thus the lockup is too early and when the lockbar flexes because you whacked the spine it doesn't have very far to go to slip out, I have encountered this on many knives and fixed it by removing a tiny amount of material from the face of the lockbar insert... "But how could they get that wrong?" you're literally talking about a tolerance of One 1000th of an inch, the lock inserts are hand ground at the factory to fit to the blade but these are mass produced, there is not a guy there taking an hour per knife to correctly fit each and every insert carefully to insure the exact lockup depth because time is money everywhere even china. Some will be better, some will be worse... If too much of the lockface is ground off there is another set of issues that pop up. The second way this could happen is if the angles of the lockface are off enough to cause slippage, some manufacturers (ZT) seem intent on not changing that geometry and thus have higher slippage rates but from their perspective the vast majority of their customers are not spine whacking their knives So it has not become an issue that they felt they needed to change, to them you are just using the knife incorrectly, which you are. I encounter all kinds of tolerance issues in these mid range titanium knives whether they are USA made or Chinese or Taiwanese or Italian, knife making is about very tightly machined fitted parts and there are thousands of factors that come into play with how the parts work together in a mass production setting, Reate has an extremely poor tolerance issue with the hole in the blade being way too big for the pivot they are using, they do this because it makes their knives fall shut more easily but the compromise is what a lot of people keep calling "Bearing Lash" it's where when the blade is about to close you feel this weird rattly movement in the pivot, it might even make noise if there isnt enough good oil in the pivot, it has nothing to do with the bearings, it is the hole being 12 thousandths too big for the pivot barrel... Compare the tolerances of an Arius Pivot to a Reate Pivot and you will see what I mean. Point being is that there are tolerance failures of all types in production knives so deal with brands that do good warranty work because there is no avoiding it and you're not going to fix the entire knife production industry by making a youtube video that talks about a specific tolerance issue without even really understanding what causes it.
