The Hole In One’s locking mechanism locks both open and closed. Most important, when the knife is gripped tightly during use, the lock also grips tighter for increased safety.
To open the Hole In One blade, simply press down on the lock release lever, and rotate it to either side. Continue rotating until the lock snaps firmly into place in the open position. This is a fast one-hand operation. Because there is no conventional clip, it is a completely ambidextrous knife.
