Pocket Knife Lock Strength Test

I carried this knife everyday for almost 2 years, I only rinsed it occasionally and did simple sharpening... It's the reason I'm into Spyderco today and why I carry Golden made knives.

[@pastordoogie8438]

It’s a well-designed & well priced knife...it’s made in China and the steel is NOT equal to the Japanese produced Spydercos. I carried the knife at camp for 3 weeks & it developed surface rusting on the blade.

[@TobiasBlackburn]

The distance from the pivot matters in comparing weight to weight

[@andylord89]

This exactly. The bending moment induced at the blade-lock interface is what is breaking it, not the weight applied at the end of the lever. With the handles of these knives averaging 3-4 inches in length, a difference of 1-inch when it comes to load placement could result in 25-33% differences in torque generated at a give weight load.

Very true however my takeaway is that all three locks performed beyond realistic use requirements. Experiment successful. Just go with your personal preference if it’s a quality knife it’s safe.

[@manstersr]

True but it looked like they had the cable placement fairly even so I don't think the results were skewed much at all.

[@MarshalNey13]

you can't take an average when you max out at 380

[@fnangfteck8193]

It’s fair for the liner and frame locks which also failed at 380, but not for the lockbacks.

Yes right? All these debates about what is safer. Have you ever put over 200 lbs of force in the OPPOSITE direction in which the knife is supposed to cut???

[@shaftwood]

Just the shape and placement of the pull cable on the handle of each knife is going to change the test and make it so the force meaurements aren't comparable. Better to put a pipe on each knife handle so the torque on each lock can be standardized. You'll also be able to break each lock with the longer pipe under the same weight and take the handle strength out of the results as well to get a fairer comparison. But, the results are pretty much as expected. Lock backs are probably the strongest, they are just heavier and more expensive to produce.

[@mattlarosa5737]

The entire concept of torque was left out of this test... Very disappointing

[@BudgetBugout]

Very cool stuff. My buddy at work had a liner lock fail on him when he was pressing down on it trying to cut something. He had to go to the hospital and get stitches. Having a reliable lock is important.

[@Powerpickle68]

Was he trying to cut with the back of the blade?

[@eloncalvin2359]

@Kyson Pablo instablaster =)

[@gavkoo]

very cool video guys. one thing to consider for future tests is the distances from the pivot you're hanging the weight at and the position of the lock from the pivot. because just for an example(if my school physics memory serves me well), if you hang 100 pounds 2 inches away from the pivot and lock is half an inch from the pivot, the lock is actually taking forces 4 times the actual weight so 400 pounds...

[@BladeHQ]

We tried to make sure that the positioning of wire was relatively the same length out, though this was more of a generalized test than a perfect one.

[@joeypruitt6304]

The physics term for this is torque. Torque is just a force (hanging weight) applied at a distance (distance from pivot). So Torque=Force X Distance....So 100pounds X2inches=200in-lbs...Just like a torque wrench.

[@michaelbradley7529]

You can't average the locking strength starting at the point where the lock failed. You have to start at the last point in which it did not fail. Also you kept referring to the locks fail weight as the weight it held to.

[@robertwatt285]

I suspect there is metal fatigue going on. Wouldn't it be better to use a new knife at each new weight to exclude metal fatigue?

[@stopstickers]

Benchmade Axis Lock please :)

[@zunedog31]

There are tons of these on Benchmade's YT page.

[@stopstickers]

zunedog31 Agreed but a neutral party test would be nice. :)

[@zunedog31]

Spike T They put the knives in a Chitillin which applies constant downward force and reads out the exact amount of pounds before it senses a lack of resistance. It is a far more exact test than the one here and is the same neutral party or not.

[@cfltitan]

zunedog31 yeah but they could have a special "ringer " that is a little more beefy than a random, off the shelf blade. I'd prefer to see this test done by blade hq on them.

[@cfltitan]

I don't ever trust a manufacturers tests. They'll build special ringers or break 100 knives until they get the one that they want to show off ad's them upload that video. A manufacturer test is ALWAYS gonna be skewed.

+Peter Bednar Definitely. This gave me extra assurance as I recently received my custom buck 112 with S30V in the mail. So glad I purchased it.

[@c.m.b.4868]

+Peter Bednar Never been a fan of Buck, but I did own a couple Case knives over the years. (never had a single failure in that time) I recently replaced the Case after 20 years of abuse (the others were lost). Looked at a bunch of different knives before I settled on the Cold Steel Recon. Got both the 3 and 4" version and couldn't be happier with my decision. The Triad locks really are the best, but certainly not the greatest for closing one handed. It's a trade off I'd make again in a heartbeat. Ease of closing isn't the most important aspect in whether or not I'll buy or carry a knife. Lock strength, durability of steel, and ease of opening are more important. Cold Steel Recon fits that bill for me.

[@juryrigjohn9697]

@@roberthall5602 accurate from my experience as well

[@kimboslice130]

This test is mathematically inaccurate. As a calculation of the average amount of weight a lock can hold, the values for breaking locks should have been reduced to the last amount they actually held. For example, in the lock back category, the Gerber held 300, not 350. The others held 380, they didn't break at 380. Corrected values are: Lock Back 353 lbs average, Frame Lock 260 lbs average, Liner Lock 210 Average. Relative values did not change, but actual average amounts did. +1 to Gav, +1 to Mike Bradley.

[@BladeHQ]

We decided to be generous with the knives and give them the weight they failed at since our increments were going up by 50 lbs each time. If we had smaller weights and more time we could have been more accurate.

[@kimboslice130]

KnifeHQ Thanks for the reply BladeHQ. I only pointed it out because the blades that made the max were calculated to "actual held" weights while the failing blades were given the benefit of the doubt. I was just saying that they should have either all been given the benefit of the doubt or they should all have been calculated to "actual held" weight. Still love the video.

[@707SonomaComa]

For some reason I'm worried about a liner lock on a karambit knife. With impacts coming from all angles it seems like it may fail more easy. I would feel more comfortable with a lock back design.

[@CliffStamp]

Spyderco was one of if not the first manufacturer to do this and published the break points. For a short time there was an arms race to produce the highest lock strength which even exceeded 1000 in.lbs . However it is a next to meaningless measurement because in use locks fail mainly by instability and no one can apply 200+ lbs to a knife in a strength linear load so side or lateral loads will be the dominant failure point in hand. Hence why it is easy to find reports of locks breaking and even more releasing but it never takes near that kind of force.

[@Prometheus1111]

quick sharp force seems to affect locks more drastically than slow loads.

[@ajopasoij9d00]

Great test.. I've got the cold steel voyager and it's extremely solid. The Buck Ranger really impressed me.

[@jonkalashnikov2625]

I've had liner lock knives fail on me before, and seen them fail on others. Lockbacks are always the best!

[@VAknives]

Did you fix the weight from an equal distance from the pivot on the folders? its the moment that destroys them so a slight difference in distance between the different folders could easely mean +- 50 pounds or more.. interesting test though and I thinks its a great service KnifeHQ

[@Vnbsm]

yea i was thinking the samething, you can make a bad knife look as good by hanging closer to the pivot

[@roninair]

This a great test for lock strength....but I don`t cut that direction ,what about a stop pin test in the direction of a cutting motion to duplicate cutting ?

[@manstersr]

Very good point and observation. I didn't think of that. I guess the main reason is everybody is worried that the knife will close on their fingers since they are right where the blade goes when you are holding the handle. If the stop pin breaks you wouldn't normally get cut. I had a cheap Frost knife stop pin break when I was cutting cardboard boxes down once but no injury. Just tossed it into the trash and moved on.

[@emiliochavez5121]

Lock back has always been my favorite, I like not having to put my fingers in harms way to close the blade... Who here hasn’t cut their thumb closing a frame/liner lock at some point?? Be honest

[@jacobslyker1450]

Cletus Kasady they make some bad knives, but they also make some great knives. The strongarm, 06 auto, and lmf II infintry are great examples of this. Even their budget knives are okay. I carried a mini paraframe for a year before I lost it and it never failed, knife was 7 dollars. Sure, it had cheap steel, and it couldn’t be opened one handed, but the lockup was good, there was no blade play, and it took a pretty nice edge all while fitting well in my pocket and not intimidating people when pulled out. So yeah, gerber makes some bad knives. But they also make ok budget knives and some pretty great mid-price U.S. made knives.

[@rico76]

@@jacobslyker1450 Agreed, all my Gerber blades ended up breaking or becoming so wobbly I couldn't trust the lock anymore. That said, I got more than my money's worth of use out them. And I still always keep one handy as I get a couple each Xmas at Walmart or online for dirt cheap during Black Friday. It's my go-to for daily utility tasks cause I don't care if i dull it, scratch it, bend it, chip it, break the tip, or break the entire knife, haha. My Emerson CQC6 handmade combat folder is strictly for showing off and defensive use only, same goes for any of my carry blades that cost over $100 really. Gerbers, CRKTs, and Kershaws are the best utility carry blades you can get for the money. I know there's many other brands with quality, budget blades I'm not mentioning, just making a point that cheaper blades are good for what they are intended for, just gotta keep a nice sharp edge on them, of course.

To be clear .. its not spydercos fault.. its the lock itself... Any slight goof in the angle of the lock surfaces will cause failure.. anf that means the slightest wear of the contact surfaces will cause the same fail... Its really a small window.. thats why production knives have trouble with this.. and even high end customs... The tolerance is the problem in production, and the wear is the problem in the custom.. liner locks are garbage. Frame locks are better because the thickness of the lockbar.. they resist vibration better. And allow more material contact between the surfsces.

That was a lot of tests in a very short video. Kudos to production crew. When I was a kid my step father's Buck lockback failed and the blade cut into bones of two fingers. A few stitches and they healed quickly. 20 years later he lost both fingers when his glove got caught in a drill bit extension.

So you guys did this test with 0 eye protection?

[@BladeHQ]

tim moran Just for the first round, after that we didn't forget to put it on.

[@cogitaretoo]

China's High End EDC I was gonna say that too, lol. You guys make good videos; don't want anyone blinded!

[@shmavey94]

Not to add to the "controversy" but in the case of the lockbacks, since the strap holding the weights were over the lock wouldn't that press it down helping to keep it in place?

[@Vextos]

Spyderco!!

[@wallman117]

Would be curious to see if the CRKT auto lock thing actually makes a difference

[@scottydirkers7855]

Kershaw never failed.

[@tacticalidiot175]

Thank you for noticing

[@nelson1tom]

Did you make sure the distance at which the weight was applied from the lock was the same for each test?

[@BladeHQ]

Tom Nelson We tried and were pretty close on most, though a few of the handles made it difficult with they way they were curved.

Could you guys do this with ball bearing locks, axis locks, compression locks, opinel? I know it's not as common as those 3 but it would be interesting to see how they hold up.

[@BladeHQ]

helder gaspar We are working on a second lock test, so you'll likely see some of those soon.

[@VinEllis]

KnifeHQ Hope you test a balisong.

[@Thomas-rp9qp]

How far from the pivot was each weight placed?

[@shoafj]

I immediately thought about the quality of the materials in play. I wonder about the results for some of the higher quality knives. Would a Zero Tolerance frame lock act the same as these? What about a test of Benchmade's Axis lock, SOG's Arc Lock, and Spyderco's Ball Bearing Lock?

[@trevorfielding7910]

I loved this! Keep em coming!! Two problems I saw: First, you can't get an accurate idea by stopping at 380lbs. And second, Cold steel's Voyager uses a Tri-ad lock, not a common lock-back lock. The tri-ad lock is designed differently and is much stronger than a normal lock-back lock so that specific test wasn't accurate either. Other than those two things I think it was really interesting to see how the different locks preformed just between manufacturers. That shows that the material had as much to do with the strength as the actual locking mechanism did.

What is the pressure exerted when batonning wood

[@MakingTheCut97]

I want to see this again with axis lock, compression lock and button lock! Also a play of between a Chinese folder, a £50 folder, £100 folder and a £250+ folder! Maybe one on full tang and tat tail etc. great video

[@Seakaye2s]

What an awesome idea for a video. Great job bladehq

[@ianarno]

Great test and editing.

[@JohnWilliams-pn7ft]

Just got the blue spyderco resilience with the s35vn steel. Curious how that would hold up. Was never a spyderco guy until this one.
