Lock Strength Test

Very sloppy set up for a test.

The knife blades slipped in the clamp/vise and the cable was allowed to slide on the handle changing the leverage.

Fun to watch but the liner lock result was flawed. Rest were pretty funny to see.
Tough knives!
 
I thought it was interesting that the lock on the Delica was stronger than the blade. The Delica is a light use knife and the lock held up!

Tests like these actually help us move forward with knife evolution and make things safer for all of us.
 
My thoughts exactly, Doc. I was very impressed, and it also looks to me like the only way to make some locks fail is to break the knife. Most of my folder collection is lockbacks, and I certainly haven't bought my last!
 
It's a pretty flawed test but kudos to them for trying to be fair and for spending the money to do it. It's hard to get any good information from it but it was a good watch nonetheless. Regardless of the lack of rigor, it showed that every spyderco knife they used had locks that work well enough for almost every real person. None of them performed poorly. It's good advertising for spyderco even if none of the tested knives could withstand thousands of pounds of pressure or whatever.

I'm more concerned with the two CRK knives failing with some really light pressure due to them being considered the gold standard for pocket knives according to the judges at blade.

I'm pretty sure it was less than 30 lbs of force that cause those locks to slip in the cold steel video.

We're going off topic, being that this is in the Spyderco Forum, but if there was a real issue with CRKs, there would be numerous reports over the forums, as the Sebenza has been in circulation for a couple decades. I take one video for what it is, one video and give it the same amount of value I give any other single piece of evidence. I mean, I carried and used a CRK as my primary EDC for about 7 years without issue. Does that not count for something? I know my real world use is a lot more real world than the CS video.

Like someone on the Spyderco forum pointed out, the cable around the handle in the placement where it was on the handle, 1" from the pivot, actually held the lockback bar in place so it could not release. Either the lockbar tab, or the blade had to fail.
 
Liner lock was listed as the worst, but was the only knife that didn't close.

Its a sloppy fixed blade now, but it never closed.

seems like a silly test, if the knife is used properly it's not an issue.
 
somethings weird--the stagnant test in the first video showed the tenacious holding 380 lbs....as much as the cold steel voyager. Now they said it held 200 til it slipped off? And whats with the slipping off factor? Just cause the lock bar bent and it won't close anymore doesn't mean the knife closed. Was really excited when I opened the link and now I'm bummed!
 
Is the lock on the sage the same as from
the Gerber Bolt Action made in the 80s?
 
If you need the lock on your knife to be THAT strong, perhaps it's time for a fixed blade?
I can't imagine how people with traditional knives don't cut their fingers off every day...

Though I'm a fan of strong locks, I can also agree with this sentiment. Part of why a small fixed blade has been a part of my EDC for years. Waiting on a SE ARK.

They do cut their fingers off every day; but when it happens they can't come on here and type a post about it. No fingers.
 
This test is silly to me. I won't ask a folder to do a fixed blades job and I am not sure what the value of extreme lock strength is outside of MBC. I survived for decades with a SAK and have done all sorts of things from bushcraft type work to field dressing a deer with one. Don't get me wrong, I would always favor a locking blade for safety but I have never understood the need for or obsession with extreme lock strength.

Also, why are these tests always spine tests? I usually apply most of the force to the edge, not the spine. I understand the fear of a knife closing on your hand but I don't do a lot of forceful stabbing and I rarely (never) whack things with the spine. Unless you are into MBC I just don't see the need for it. It seems like marketing at it's finest selling me something that I don't need.

Thanks. That's pretty much everything I think on the subject but I was too lazy to write it all.
