ABSTRACT:
A knife is described including a handle with a blade mount. An elongated blade with a handle mounting surface is releasably engageable with the blade mount on the handle to enable selective attachment and detachment of the blade to and from the handle. The blade mount includes a blade back configured to receive a length of the blade and a tang disposed within the handle. A blade release is formed integrally with the tang and includes an integral elongated bar spring extending longitudinally within the handle from an end joined integrally with the tang, to a laterally movable free end. A blade lock is located on the elongated bar spring adjacent the movable free end, laterally positionable by deflection of the elongated bar spring to selectively engage and lock the blade in an extended operative position, and a release position clear of the blade.
