I received a new leek from kershaw about a week ago. It was stiff when i got it, but i figured it would loosen up some. Well, about 3 days and probably 200 flips later, it still took excessive, concentrated force on the index flipper to get it to lock open. I tried to loosen the pivot screw, to no avail. Next i took the whole thing apart. I cleaned everything and polished the bronze phosphor washers, then lubricated everything with a graphite lubricant. I think it's actually worse now. No amount of force on the index flipper will get the thing to lock. I tore it apart again, this time inspecting the torsion bar. It was rubbing very hard against the frame, so i adjusted it slightly and put it all back together, to zero effect. I'm stumped. Any suggestions? I really feel like the torsion bar just doesn't have the oomph it needs, as the action of the hinge is smooth. I did however notice that the blade occasionally binds on the pivot right before lockup and actually turns it. is this normal? Should i try a different lubricant? I've never had to apply extra lubricant to my other leeks. I'd really appreciate any advice on this one! sorry for the long post!
