Claim:
A folding knife, comprising: a handle; an axle coupled to a first end of the handle; a blade rotatably coupled to the axle, the blade comprising a working portion and a tang, the blade having an open position in which the working portion extends from the handle and a closed position in which the working portion is substantially received within the handle; a lock translatable along a path between a locked position in which the lock prevents rotation of the blade by contacting the tang and an unlocked position in which the lock permits rotation of the blade; a spring arm in the handle, the spring arm movable between a first position and a second position, the spring arm biased to the second position; and a safety coupled to the handle, the safety movable between an on position in which the safety deflects the spring arm to the first position so that the spring arm blocks the path of the lock and maintains the lock in the locked position and an off position in which the safety permits the spring arm to move to the second position so that the lock is free to move between the locked position and the unlocked position.
