Yeah I really feel like the EDC community has become a bunch of snobs that don't use their tools and just take pictures of them and post them on Facebook or whatever. I mean I went to Ace Hardware the other day and picked up a Spyderco dragonfly 2 and a Spyderco Stretch 2XL both in black FRN and VG-10 for $140.00!!! Everyone was like " it's not a PM2 in Titanium so it sucks and VG-10 sucks!"...really? Vg10 is probably the best working man's stainless steel out there still.. even more so since "super steels" keep popping up every other day. And Since when did having a steel you can't sharpen yourself become cool? I hate the super steel trends. Give me anything from D2 to S35VN and everything in between and I'll be happy.

The only problem I have with this test is how quickly the load is applied. in my experience scales, especially digital scales, are not accurate under shock load. kind of like when you step on your bathroom scale and it takes a second or two to level off and give an accurate reading. In my opinion you should try using a hydraulic system, that is more capable of applying slower, more steady loads. I would definitely love to see more videos just a more accurate rig. Keep making great videos.

Weight is the force, an object is drawn with to the center of the planet. A scale meassueres force, when you step on it, you briefly apply more force onto the scale. When you stand in a trampoline, the sheet will sink in a little, when you add momentum and jump on it, it will go down much futher. Also, a slow test would be unrepresantative, because i doubt, that anybody is able slowly apply so much force from their wrist, imho.

8 years late but your exactly right and the nature of a lockback defeats the purpose of the test as well. all other locks fail in the direction they disengage and the wire over the lockback prevents this the way the test is set up completely skewing the strength of the lock. instead you are measuring the weakest point in the materials

That said, I do wish you'd disassembled the knives afterwards, particularly the Ball Bearing and Bolt locks, to give a bit more information about the failure modes. I'd love to see what happened to that poor bolt. Also, perhaps next time you could vice the handle, and thread the wire through the Spydiehole, for more consistency and a more realistic test?

I'm not a physics expert, but I do think this test is flawed in 2 ways 1) Inconsistent grip You can see in the slow-motion video of the framelock, the loop slides up before the lock gives way, which changes the force's leverage. The further the force is applied from the fulcrum point, the more mechanical advantage it has, less force is required to do the same work. 2) Direction of force I find it weird that you're testing the force from the handle and not from the blade. I'm not sure if it would actually make a difference, but my guess is that would be a difference in lock strength when the force is from blade to lock rather than lock to blade.

And that’s exactly where your thumb would be when your actually using he knife. So it didn’t really fail. It proved as long as heir is pressure there as under normal use that lock will hold till you break he blade. So really it’s impressive. It just depends on how much pressure you can keep there with your thumb and wether you accidentally hit the release or not.

Well it didn't fully succeed, lol. But yes it did protect the hand which is most important. The problem is, all liner locks are so much different and how safe/strong a liner lock is largely depends on the precise specifics of the lockup, concerning materials, friction, % of lockup, angle of liner at lockup, shape of the end of the liner/the part of the tang that accepts it, stiffness of the liner, how well the liner is attached to the scale, how strong the scale material is, how tight the lockup ultimately is, etc etc etc. Some liner locks are complete trash. I like the liner lock on my spyderco military. It is done quite well considering how lightweight it all is. I've never had it fail, but I do prefer my framelock military. It feels more secure, with how tight the lockup is, and the amount of friction keeping it locked in.

+KnifeHQ Thank you for this great video! That you attempt to standardize your methodology, and give the caveats you do as to the efficacy and interpretation of your experiment's results are also both encouraging. I wonder whether the sampling used to determine the multiplier can be considered valid because you state that you arrived at it from but one example. I wonder whether it would hold true as considered against both multiple comparisons between the two tests upon the same model and as between the data differences of those tests done upon the other models--you don't state that here. Interesting and entertaining, nevertheless. Lastly, I do wish that you had included all the data you gathered from this experiment--particularly the failure weight of the two lockbacks. That the item didn't behave as you had hoped by no means invalidates the data here, the weakest link remaining the weakest link. While understanding the reasoning behind your not including the actual data, that you place some imagined, hoped for, but not actually arrived at unknown in your final graph undermines your product here a bit and demonstrates the benefits of double-blind studies as well, IMO. Just my "two cents." Thanks again for the video, and for all of your excellent work.

Check out 11:55 to 11:56 . The cable slid up the frame lock to the 3rd screw on the handle. About 2x the original distance . Hence more then twice the dynamic torque. Not to mention the point is not static but dynamic due to the changing toque arm. Test results are not accurate.
@austinbrown7757

well in a lockback design, the rocker arm has to lift up to disengage the lock, so wouldnt the loop strapped around the knife be holding the arm down not allowing it to lift up, therefore pushing the blade to the point of failure rather than the lock?
@austinbrown7757
@austinbrown7757 8 жыл бұрын
to explain a little better, im saying the loop that is pulling the rocker arm down is forcing it to stay in the engaged position with just as much force as is being put on it. it basically took the strength of the lock completely out of the equation, turning it into a test to see what else on the delica would break if the lock strength wasnt a factor. lol

@@BaritoneMonkey Weight is a specific vector of force. No one said anything about mass. From an engineering standpoint, you measure force.

Perhaps more accurately, it's the moment about the pivot that is causing the lock to fail.

I would still trust the frame lock on the Kershaw Cryo 2 from the first video. Even though it technically failed duh to the fact that you couldnt release the frame lock, it was still a safer lock. Most of the other knives closed when the lock failed, but the frame lock on the Cryo did not allow the blade to close. The whole purpose of a lock is to prevent the blade from shutting on your hand. Therefore the frame lock on the Cryo is one of the few that actually stopped the blade from closing, even when it failed. Therefore i trust this knife lock more than the others.

Friend of mine did his own test with his own winch that is similar to the one you guys seemed to use, bolt lock and lockback were the strongest, the liner lock was the weakest and the compression lock was significantly stronger than the ball bearing lock. The compression lock was the most different, came in at 235.74 pounds, ball bearing lock was significantly weaker at 121.18 pounds. What he did was put it at where the lock engages which is the best way to actually test. The delica btw was 382.68, very impressive. Bolt lock came in 401.20

But regardless, its a fun youtube video for views. Some people like watching things break, thats why channels like HowToBasic and TechRax exists. Do you need to test how long you can boil an iPhone or an S8? No. Its for entertainment. That being said, idgaf what you do to your stuff, just dont be putting 200lbs on my Delica 4 or my Pixel 2 and were good.

It's cool to see them doing some tests, and credit to them for doing it, but it's also testing the locks under best case scenarios too. Few locks fail under steady pressure middle of the knife like that under any normal use, but sharp impacts, done from less than ideal positions on the handle, and of course not at a straight line to the lock, etc. More realistic failure scenarios would be more telling, but credit to them and addition of the dynamic force much more realistic and telling!

+Fappolice The Spyderco Ball Bearing Lock works exactly like the Axis lock. The only difference is in the spring that pushes the lock. IMO, Spyderco only made the Ball Bearing Lock to create some competition for the Axis lock. If you look at 6:56, you can see that not only is the design of the lock extremely similar, but even where the blade contacts the lock is the same design as Benchmade (7:03). It is a blatant copy. If you are a Spyderco fanboy, you'll just have to get over this fact.
