DOUBLE LOCK MECHANISM: One blade, twice the safety. During standard use, the Liner-Lock automatically engages and locks the blade open. But when you need to make more rugged cuts, push the Double Lock switch forward to block the Liner-Lock from possibly disengaging and allowing the blade to close on your hand. Adjust the safety detent-action (which controls how easily the knife closes) with the tension screw on the side of the knife. DEEP-CARRY POCKET CLIP: Secure your knife at hand’s reach. The COAST One Position Knife Clip makes it easy to keep your knife readily accessible while also tucked away in your pocket.
