folder vs. fixed blade

[gomipile]

How hard would it be for a bladesmith to make a replacement blade for a Tri-Ad folder in a tougher steel? Imagine an American Lawman with a full flat ground 5160 blade given the type of heat treatment used for an ABS Journeyman test knife.

Lets have someone make something like that and then put the knife through a torture test. Then we could see which fails first, the lock or an incredibly tough blade.

The Tri-Ad lock is a fascinating lock. As far as I can tell, it's exactly the same as a lockback, except with a blade stop pin. And what difference does that one extra pin make? Apparently all the difference in the world.

The original poster makes an interesting premise. If you doubt the Tri-Ad lock, you should buy expensive knives and break them in order to prove the original poster wrong.

I have to tell you, that isn't a terribly compelling argument.

Also, why is weight the most important feature for a fixed blade? That leaves blade length and thickness relatively free to vary. A very short, stubby, and thick fixed blade with the same weight would be vastly stronger. Perhaps a more useful test would be for a fixed blade of the same steel with similar hardness, and with the same profile, length, and thickness.

Well said, this is the comparison I was meaning to get across.The weight is not really the determining factor.

Sure, I'd love to see a Tri-Ad with a similar size, shape, and material blade to, say, a Mora Clipper. Then we could compare it to the Mora and see if there is a practical difference when used for the same real world tasks.

I'm fairly sure that there would be no practical difference in that size category.


Now if you were to compare a large Espada with a 1095 blade to an ESEE 5, I'll bet the ESEE would come out ahead when both were subjected to the kind of use people subject their ESEEs to.
