I am convinced that modern locks are rather strong.....even the El cheapo I got from Wally World has a straight metal piece that falls in line with the blde when open. I'm no genuous but I can't for the life of me figure out how this could posibly fail fithout the aid of a hammer. I've been fittleing with it for a while now....may be the old locks have been fixed so they will not break.I recommend a fixed blade for self defense, because a lock can break, and then you have the blade swing closed and cut off your fingers. A fixed blade can break, but it does not have a hinge, and so it won't close on your fingers, it just breaks.
Don't fool yourself. Any lock can fail if you exert enough force.
Yeah that really is a sweet blade!!!!!!!!!!My preferred blade is one I had made custom. This baby has seen work and is on its third sheath yet I keep the finish real nice. Must always take care of your knives.
