framelock failure

[sophijo]

Someone(?) mentioned that the CRS2 Ti framelock went out of production in part bcause the lock eventually failed...I was wondering how a frame lock fails? Does the metal fatigue or round off or something, and how does Reeves avoid this?

I believe that frame lock failure has somehting to do with metal wear. The Ti is softer than the hardened blade tang. I know that Strider gets around this problem by hardening the Ti where it rubs against the tang. I guess that the same thing can happen to a liner lock, I saw significant wear on my Commander where the blade rubs the lock bar. It might also have something to do with the thickness of the frame/liner. A thicker piece of metal will resist wear more, and the effect of wear would be less noticable.

I would also like to hear other opinions on this issue. I am sure I still have a lot to learn.

I had a new CRKT S2 that failed with a small nudge after some oil seeped onto the tang. It popped right off with just a quick bump and I got a good poke out of it. I now Swear by axis locks, which are completely unaffected by slick stuff on the mechanism with it's perfect 90 degree angle of the lock bar on the tang.
