ABSTRACT:
An automatic folding knife including a safety stop to prevent the blade from being released from either an extended position or a closed position. A safety stop is operated by a control element located on and movable along the back of the handle of the knife, while a button that operates a latch to release the blade is located on a side of the knife handle. The safety stop includes either a lever or a disk movable by the control element into an engaged position blocking movement of the latch button and thus preventing the latch from releasing the blade. A detent holds the safety stop either in its engaged position or in a disengaged position.
