Abstract: A knife comprises an elongated frame defining a blade passage and having a forward opening at one end of the frame. An elongated blade is received in the frame and movable between an extended and a retracted position; and the blade has a point at a first end and having a first blade portion extending from the frame when the blade is in the retracted position and a greater end position extended from the frame when the blade is in the extended position.

Abstract: A locking folding knife includes a handle; a blade pivotally coupled to the handle, and moveable between a closed position and an open position; and a locking device movable between a locked position and an unlocked position along an axis generally perpendicular to a plane defined by the blade. A tang of the blade has a substantially planar locking surface, and the locking device has a corresponding substantially planar blade engagement surface. The locking device secures the blade in the open position when the locking device is in the locked position, the substantially planar blade engagement surface being abutted with the substantially planar locking surface. The locking also comprises an offset post providing the additional advantage of design flexibility.
