Strangely, my Ti-Lock was the only CRK knife whose lock I wore out, and it became actually “jiggly”, with major up/down lock-rock.
CRK replaced the spring and bronze dumbbell free of charge. Be aware that if you daily carry a Ti-lock, this may happen. In my case, the bronze dumbbell became worn and no longer sat firmly in the lock cavity.
I gave up on the idea of daily carrying a Ti-Lock after this, but still have the knife and carry it occasionally.
Thanks for the heads up. Mine is doing pretty good.
