Leatherman ARC closing mechanism critical failure!

Possible Flaw in Leatherman Arc - Locking Mechanism Wearing Down It's possible that it's just my defective unit, but if not, Leatherman might have a serious problem on their hands. The locking mechanism on my Leatherman ARC - the protruding tabs integrated into the pliers - has worn down the steel on the frame of the tool to the point where the locking mechanism on one of the arms has stopped holding. This defect occurred solely through opening and closing the tool. Nothing more. Please check your own tools and let me know if I'm the only one who's been unlucky... P.S. Excuse my English - it's not my native language, so I make mistakes when speaking without preparation.
