Discussion: Scale/Liner Based Locking Mechanisms

I really wanted to highlight a few misconceptions about scale/liner designed locks.

I think any folder will have a threshold as far as lock strenght. That is why God made fixed blade knives!!

@TacticalTupperware I think you mean "humans." :D

Well done video. It's nice to have you back, i would like to hear your thoughts on the strengths and weaknesses of the lock-back design.

Endura with FRN vs. G10 Endura vs cold steel's Tri-ad lock...and so forth.

you the man, keep the videos coming.

@LordAsgard8 I would like to make a video on spine-based locking mechanisms. Though sadly I only have experience with the mid-lock back style (Bryd, Delica SS, Endura SS/G10, and Endura FRN). I still haven't tried the triad, front lock, back lock, or even the Italian Stiletto lever lock. I think I might also be missing a few other styles.

I'd love to see a weight test on a sebenza. I've always wondered why knifemakers put such thick lock bars if they're just going to mill out part of it to be as thin or thinner than a liner lock.

@aHippieWithKnives Well the reason for the lock bar cut out is so they can stress bend the Ti easier to make the lock. It also means, for the user, the lock will be less stiff and easier to disengage. Also when opening the knife, the ball detent will have a balance of holding the knife closed and allowing the user to open the knife. Stiffer lock means the knife will be harder (and less smooth as well since the detent will contact the blade when opened) to open.

@SharpSpears Also, the only reason a lock is needed is because the pivot is smooth. Thus, with no lock, the blade will purposely close, not accidentally. Friction folders work because the act of cutting forces the blade open, no way to accidentally close the knife, until you purposely close the knife.

[SharpSpears]

@Zigosity That is true. But people still believe that they do and many are advertised in that way.

As far as abuse, my saying has always been, "a good knife can cut, a great knife is your (wilderness) tool." If I'm paying upwards of 200+ for a folder, I expect it to be a great knife that can take some punishment even if I know the knife has far less strength than a fixed blade.

[Zigosity]

Honestly, locks on knives are to -prevent accidental closing-, nothing else. They are not designed to support weight, withstand large impulsive forces (spine whack), etc.

Use the right tool for the right job! If you need a fixed blade, use one. Don't abuse the poor folding knife :(.

Solid coherent facts.
