I also have had trouble with lock-stick. Really bad. And unless I flick the blade open fairly hard, the lock-bar will barely slide onto the tang. On several occasions it has even failed to engage at all, enabling me to close the knife with out even touching the lock. I am the second owner so I am curious if I have any recourse at all, as far as repair or replacement.
Oh, and the when trying to adjust the pivot screw, the whole pivot just spins.
Other than the lock and pivot, this knife looks, and feels really nice. The opening action is smooth and the blade is centered. I really want this knife to use in my EDC rotation, but those flaws are keeping it in my Spyder Pack.
