yeah ikr

Agreed. And would like to see some working man review some knives. Everybody on yt has nice pretty pink clean hands. Not a single callus.

@@butchcassidy3373 100 % agree

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.

@@butchcassidy3373 only thing they have are cuts from clumsily handling their fidget toys

Mild damage to the lock.

@@alextsukada4013 “needs lube”

Resale : $190

Shear failure

Depends on how good the metal is.

well actually the lock back only failed when the blade broke. so a fixed blade would have the same weakness.

@@samlee6240 Nah, a folder has a much weaker spot at the base of the blade, where there's a hole for the pivot and cutaways for the locking mechanism. A fixed blade, especially with a full tang or even integral bolster, has a much more sturdy construction in that area.

depends... compare some sog rat tail or mora that are not even full tang, with triad lock

Yeah like, kinda cool that they did this video, but why publish it if you know your results are off by a factor of 4 because the winch builds tension much faster than the sampling rate of the scale.

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.

@@gehtdianschasau8372 I don't know anyone (who isn't an idiot) that uses their pocket knife like a hatchet, applying huge amounts of shock load To the pivot, and locking mechanism. Most cutting situations are slow, consistent, and steady application of force.

@@BryceAWD It's been 4 years, so you might not remember that this test is about the sthrenght of the locking mechanism when the knife is open. I don't know anybody who cuts with the spine of the knife.

@@gehtdianschasau8372 look up sampling rate. I'm not going to wast my time arguing with someone that doesn't understand what they are talking about.

dmp762 of course they don’t. Coldsteel and the Tri-ad lock will win every test. Some may dislike coldsteel but they are in total denial if they think anyone else is building better stronger knives. Cold steel 4max 👍👍

Cuz we already know

No need. Already proven.

Brian's Life Now, if they only gave enough of a crap to clean the grit out of the mechanism before selling it to their customers. That would be awesome.

Nah, they're afraid to get sued 😂😂😂

+Lorenzo Giancristofaro Seems to me the ball bearing lock didn't even fail. The handle did. The screw broke allowing the ball to come up between the liners.

Ze Doktor I was expecting it, a steel ball bearing as insanely hard to brake, the pivot screws hold far less weight. The thing is that since the scales broke there is no way to use the knife ever again

Your fingers, however, will NOT be usable after such a failure.

I'm surprised the ball bearing lock did so well

Why don't they use that type of lock for karambit knives?

Braindead comment

That would be perfect. Same dimensions and level of quality.

PowerMadHeadBanger Or the blade will break

They did that in part 1 and the CS maxed out @ 380 lbs.

@@amadeospapa5673 yes but they didnt use the winch

@@josefstalin9678 true

That’s wat I wana see

evvignes not to mention the liner lock is the only one that didn't fail. Sure, it can't be closed anymore, but it's the only knife that you still have your fingers as well

evvignes exactly. I don't count a folding knife's lock sticking in place as a fail. If a knife is going to "fail" that is the best way for it to happen. Much better than the blade snapping off.

evvignes they are also​ testing the opposite direction a folding knife would be used in real world usage. the entire test is flawed.

thank you

Rob Kahla The liner locks did fail the test. The knife just got lucky and you could still use them after but with some damage, the lock still failed. The lockback didn’t fail because the blade failed first so the test was inconclusive since delicas have a much thiner blade than all the others.

You are correct. The lockback test is seriously flawed.

You both are seriously flawed. The video clearly shows the cable at and slightly above the pivot point of the lock bar. At the pivot point, there is no bar that ever rises above the handle. Above the pivot point, the bar recedes into the handle when pressed.

Good observation!

@@WhiteSandsMbuna no they arent flawed you are flawed xD, the location of the cable means the lock is being forced closed, so the lock cant be opened, its like measuring the force required to open a door inwards while you are pressing it outwards

+The Late Boy Scout Yeah super psyched they used all Spyderco

Ikr?

the Triad lock is probably the strongest but it's a bear to manipulate sometime I don't like it. it can snap shut on your fingers..a Triad lock is really not a one-handed knife.

John Monroe It totally is a one handed lock. Depress with thumb knuckle, blade drops on finger with choil, close. Can flick it no problem

John Monroe thats not true at all, my spartan is one of the smoothest knives i own, they do take time to breal in but to say theyre not one handed openers means your ability to open it is the problem or your knives arent broken in or oiled

Dustin Bell is their a grove lock? geddit😃

LOL Nick, you are so right! It seems no one is doing any even half baked scientific testing, maybe Benchmade? Here it was not determined when the deformation started and ended and the force profile of deformation. Besides that as you say for every day use these locks are more than good enough.

In what fairy world populated by unicorns and little bearded dwarves wielding giant axes do you live in that a company is obligated to promise that the product will perform when abused and not used as designed? In short you’re a moron.

The testing is flawed whenever you move a load farther from the pivot its going to need less weight to break and the cable kept sliding to a farther point from the pivot

@Joker Toker I guess if you like hanging off your knives against the lock? Which i have no idea what use that would be putting pressure on a folding knife in that direction.

I read this in your voice. Dunno if I should feel good about that. LOL

Exactly.

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.

The Ace so you use your knives with pressures of 50+ pounds? Lol how do you know how strong they all are without knowing true strength of the blade materials etc....

For shock loads, i sometimes nimoticed the liner lock to slip to the left leading to disengagement. So it has 2 different ways of failing

+MrSottobanco Yes, unfortunately the wire slid up on the frame lock a bit. As stated not perfect.

Espada Hunter but the test also proved as long as you apply pressure on the lock where your hand or actually your thumb normally will be the lock will hold very well.

@@whatfreedom7 Except the lock is the reason for a blade failure. The rocker puts pressure on the thinnest point of the blade steel, which is a design flaw required for a lockback. I'd rather have a functional blade that had a lock failure than two pieces of scrap.

@@hunterf9768 since this was a test exlusivly of lock strength the Lock back was the strongest the blade used wasn't the best design to use for the test (put a Buck 110 in its place with a bulkier blade profile and the results would differ)

but the cable is behind the pivot point of the rocker, so it doesn't hold it down

Good call

doluseb Yes!!

There are plenty of other tests showing that frame locks really aren't that strong when compared to something like an axis lock or back lock.

Probably similar to the bolt lock. It's an extremely tough design, and would most likely break the blade before giving up.

axis lock is strong! in fact, in the benchmade tests, the liners deform and the d-nut(not "deez" nut) that make uo the blade pivot completely breaks. that lock is too damn tough for the rest of the knife! lol

Spyderco doesn't use axis lock, come on dude.

Sasquatch78 please tell me that was a sarcastic joke and you weren't actually trying to tell me that spyderco doesn't use the axis lock....

Mike D Nope, they have the bolt lock which is similar to the axis lock, but it's not the axis lock.

Good point on number 1. On your second point, it should not be any difference as long as the grip can hold the blade or handle steady.

Duh! Why didn't we all realize that! Good eye man!

+Logic Bob ironic cause your name bro...

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.

I think a properly-made plunge lock might be stronger.

glad to see someone mention this

Weight IS force though? Which is why when you weight less on the moon or underwater. You're thinking about mass, which doesn't change.

@@BaritoneMonkey Weight is a specific vector of force. No one said anything about mass. From an engineering standpoint, you measure force. The force is applied by weights, but the lock would fail at that force threshold regardless of orientation, which is why it's more useful. Perhaps more accurately, it's the moment about the pivot that is causing the lock to fail.

@@danielhesse8600 got it. No, you're right then - misunderstood your initial comment. Have a good one

ANDROID HACKING 101 and the lock back failed in such a way that, well, the blade disconnected from the handle which guarantees safe fingers

I’ve had a CRKT liner lock fail and close on me. Luckily no fingers were lost.

Delica 4 squad where you at?

Well by that theory the delica is by far the safest knife since their is no blade at all to cut you. 😁 unless of course it flies and stabs you in the eye or ball sack.

I had a Kershaw liner lock fail on me. Have a great scare to show its doesn't always happen this way!

+Hiluxtaco yea or other steels like a ZDP, superblue, etc

+ting280 I agree, since it was the steel itself that failed on those Delicas.

The blade failed instead of the lock because the cable was reinforcing the lock bar along the spine of the knife.

That is a very good point. the cable in that location would likely prevent the lock bar from raising above the frame which would prevent the lockbar from disengaging from the blade.

gamer on crack! That is a good point. I’d like to see it done with something simulating more of a push and more hand like than a cable. I’d also like to see more test with bigger lock backs.

+KnifeHQ The red media not found?

+clonexili Yep, didn't get rendered before the export and I didn't catch it.

+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.

+KnifeHQ you should use like liner lock Gayle Bradley

+KnifeHQ : the liner lock didn't fail....you just turned it into a fixed blade.

Clearly you're not good at interpreting my sentence. Where did I say VG-10 is a "bad steel" huh? Can you extrapolate what I was saying? I'm not going to try and prove myself if this is just a mistake, but for once just use your brain to read what I wrote and correlate it with the video.

+MGladwell I don't think the VG10 is rust proof. Maybe more resilient to rusting compared to few other steels, but not rust proof.

***** I 100% agree with that! VG-10 will do the job well, but there are better steels with their own drawbacks.

+Fappolice steels are steels, no matter how 'high end' one is, it's still all about trade offs and how well they are heat treated. 52100 and AEB-L are low end steels but can do amazing things when properly heat treated. VG-10 is a medium carbide steel and exhibits the traits of being such.

Well, no, you could say that fine grained steels are better, as far as i know carpenter makes the finest steel

Watch the start again...

XDDD

Axis lock is stronger

I think if you for the titanium ball cage for the manix it would beat the cross bar lock

@@williams.1130 axis is stronger than both

Eli Garcia that’s exactly what I was thinking. Wtf

Its obvious there'd be marginal difference in results. At any rate, locking mechanisms for folders should aspire to be fixed blade strength when tested at the fold. Of all, that means lock backs.

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

I think you are right.

We used a Buck in our first test: kzfaq.info/get/bejne/arGde8mTrJ3eZ5s.html

wll1500 it's just a normal lock back its not THAT strong. One word "Triad"

Oh yeah with a Buck 110 that Test would be awesome

Laszlo Leo Kershaw 1050 folding field :)

Buck 110's are nothing special lol.

F Barbie

messerknartz we still learned which of the Spyderco lock systems were stronger except the delica but that’s about all we learned.

Rich L Noticed that too

Yeah I mentioned that also. How did we go from 380 to 200 both tenacious and both on their own channel? Did I miss another test

Cold Steel's Tri-Ad rules.

This!! This is exactly what I was thinking, I just wondered if anyone else had even considered this...

+gamer on crack! Yes I see that too, good spotting!

Brian Smith but If the cable was further down it would have greater leverage against the lock, making it a unfair test...

Spyderco*

It aint.

It is pointless. When will you be using your knife to support ~200lbs of weight? If youre doing that you shouldnt be handling knives as it is not only unsafe, but it hurts us enthusiasts' souls to see these works of art destroyed like that. 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.

Burak Yilmaz Agree

silat why not test it yourself? This vid was still interesting and comments like these make them not want to try new things

+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.

+Fappolice I'll back you up on that. Axis and ball are very different.

+Fappolice The way both locks work as detents and how it locks on the blade when deployed are very similar. And both are pushed by a spring. Spyderco just wanted to get into the Axis lock market. End of story.

Just search "axis lock test" benchmade has their own testing videos.

Axis is a piece of shit lock on over priced, ageing designs

It made me a little sad.

You just did, go back and look at the results and you can see how the bearing lock performed
