I've been in the knife accumulating "business" (hobby, pastime, obsession) for near 20 years, now, and it seems like just recently that I've had to deal with Lock Rock. For those who are new to knives, lock rock is when a liner, or frame-lock doesn't fully slide over to keep the knife still in the locked position. To me, it seems like an issue of not enough bend in the liner, or frame. My 2 examples are both $300+ titanium frame locks. The solution these days is to start including stainless lock inserts at the end of a frame lock to be adjustable for "wear." Is there a reason I saw nothing about this phenomenon until recently? Has it always been an issue? Did we just stop bending the bars over far enough? Were people complaining too much about Lock Stick? Let me know your thoughts... Anyway, it was an easy fix on both knives. I just took them apart, and put a little hurt on the lock bars to make 'em mind better. No more lock rock, and they didn't complain a bit.
