liner lock vs frame lock vs lock back BHQ video

I would like to see this kind of test with some higher end knives. I was pleasantly surprised with Spyderco Tenacious.
 
Only surprise was that I actually watched the whole video. I never get my blade stuck in something and then very smoothly apply all my body weight in a downward motion...great for views though!
 
That was fun to watch!

With a sample size of only 3 each, it isn't necessarily a concrete data point-- especially GivEn the pR points and some of the manufacturers represented. Not to name names, But at lEast one of the bRands is known for pretty cruddy build quality.

Spyderco and Kershaw really made strong showings with products in decidedly low end price brackets. Just goes to show what good design can do for you. It's no mystery to me why so many enthusiasts with expensive blades still appreciate the Tenacious family and many Kershaws.
 
I would have liked to have seen a Rat 1 in liner lock column. Might have upped that average.
 
I would have liked to see the Lion Steel rotolock frame lock. Wasn't suprised at all with the lock backs winning. Not suprised either with the liners locks failing either. This is why i stay away from them. Have problems with liner locks always. Framelocks on more quality knives would have done alot better like Lionsteel or ZT. I love lockback folders though too.No matter if it's high priced or low i always have problems with linerlock knives.
 
I would have liked to seen Spyderco's compression lock and Buck Marksman's Strong Lock tested. Maybe next time.

Even the shabby liner locks failed at 150+ pounds, iirc. What are you doing with them that you have problems? I beat the crap out of a Persistence for a year and a half and never ran into issues with the liner lock.

Barely anything since i can't use them. Out of the box bad for most part. Have problems with them slipping or moving past the blade and getting stuck on the other side of blade. An Emerson i have the locks slips constantly, Kershaw i had the lock would move pass the blade and get stuck from just deploying and a Junglee i had did the same thing. Was actually suprised with the tenacious in the video. Never had problem with lockback,framelock or axis and just feel safer using them.
 
I find these lock strength test to be very useless. when would you need a knife that can take a hundreds of pound of pressure in the opposite direction of normal cutting? When stabbing a bunch of them into a tree or wall to make a ladder?

My lord, what are you guys using your knives for?

Am I taking it to serious that others take locks far to serious?

Inherently strong in one specific test.

True, that's worth remembering. But as a result of how expensive knives are (and how little value they have after these tests) this marketing move by BHQ is likely among the best data we will get! I don't know about you, but I don't have nine knives laying around to destroy just to satisfy my curiosity.

Yup! Probably the only way to "fairly" compare forces though. Impacts would have too many variables.

This is exactly what I was thinking. If only the cryo came in 14C28N!!! I thought the gerber performed well though... Perhaps it wouldn't perform as well consistently, but this may be evidence enough that the gator is better in some respects (batoning) than the much more respected ESEE that was tested, which is a real surprise.

Meh, maybe. I had a Rat 1 fail on me. To be fair it took some doing... The performance of the 5.11 was surprisingly poor, bordering on embarrassing (not to say that this test is perfect, or a metric of the overall quality of a knife)

Do you only carry slip-joints and friction folders? I think this is just the best way to objectively test locks. Is it analogous to use? Probably not perfectly. You're right, lock strength isn't the same as knife strength, but that doesn't mean it's irrelevant. If it was, we'd all exclusively carry svords and SAKs, and taking a fixed blade to the woods would be overkill.
 
The results don't surprise me too much. May just be my confirmation bias at work, but it reinforces my prejudice against liner and frame locks.

Why do you want a car with a 5 star safety rating? Are you planning on ramming it into a tree?

We live in an imperfect world and accidents happen. Personally, I'm quite fond of my fingers and I'd like to keep them all.

Let's not forget this is just one data point though, and for most people who EDC a knife with either a liner or frame lock, the convenience/ease of use is worth the loss of strength.

I carry both slip joints, locking knives and fixed blades. Why would we all exclusively carry friction folders and slip joints if it was irrelevant that a lock can take 350 punds? How will one end up needing it? 350 pounds is not a little tap on the spine.

I'll use any knife with great care and don't trust the lock. It's understandable to want great engineering, craftsmanship, quality and whatnot, but I think some people expect way to much from their knives.

I would like to drive a safe car to avoid being being harmed or killed in case of an accident. It's not only up to me if my car trip is safe. It's my improper use of a knife that might harm me. I don't see how cars and knives compare, sorry.



Not trying to sound like a person who want to stop people from getting knives that can take 5000 pounds of pressure in the wrong direction. Just sharing my opinion on the need for it.
