With "hard use"being all the craze lately, I'm wondering why no one (to my knowledge) has built a knife with two different locking-mechanisms on it. It would take some mechanical refining, but I'm thinking two locks that wouldn't interfere with each other like a compression lock and a liner lock. That way, either way force is put into the knife you're good to go. Now, I'm not a believer in the "hard-use" fad, but I do think something like this would be interesting. A frame-lock and an axis-lock? Maybe two compression locks on each side of the blade and a mechanism that rolls or slides down the center of the liners towards the blade to unlock both of the compression locks at the same time. Wait, that's actually a good idea....is it? Maybe I'll draw a diagram a post it.
