I did a search and didn't find what I was looking for, though the terms "PM2" and "lock" tend to bring up info on nothing more than the compression lock (not surprised about that, really).
Anyway, I was talking on the phone this evening, and was absent-mindedly flicking my PM2 open and closed when all of a sudden the thing got REAL gritty, and then more or less quit working. I'm very puzzled by this, as I've never heard of this happening before. As I bought it well-used, I'm sure that it was taken apart already, so I wasn't worried about taking it apart myself. In doing so, I learned that the pivot is more or less pressed into the blade (or at least it appears as such on mine). It's in there good, and it's pretty hard to rotate the blade (both before I took it apart, and after). All copper bushings are present, and I can't see what would have caused it to lock up all of a sudden like that. Any hints? The blade has some very small nicks in the edge, so I've been thinking of having Spyderco resharpen the blade anyway (I don't have a decent setup for reprofiling FFG blades, and don't have the patience or time to do it with the Sharpmaker), so perhaps I'll see if they'll give it a quick once over and fix what ever's wrong for a small fee.
Any suggestions on what would cause it to freeze up like it has? I can't see anything having gotten in there that's small enough to get between the pivot and blade.
