I have had my ZT 0560 for about 6 months now... Its a sweet knife! But I notice the frame lock is closing in on the other side of the frame. Its about 3/4 the way there already and I Havnt had the knife that long. I mean I Havnt even needed to resharpen it yet.. What gives? Does the knife have replacement warranty on that? Given its Ti can't be cheap to replace. Noticed on the lock itself has a slight raise to it. Kinda likes its ment to goto that part and stop. I know Ti is strong but also isn't it a soft metal? Kinda like gold?. Anyway. I've used the knife maybe a few dozen times and bought a pm2 that now is my edc in rotation.. Just wondering about my ZT.. It Started at half way lock
