ABSTRACT:
A modular hand tool system in which a tool piece is detachably secured to a handle has an elongated planar handle having a centrally located rectangularly-shaped cutout extending inwardly from one end. The tool piece, which may take a variety of forms, has a shank portion of substantially the same shape and size as the cutout and is received therein with a tight sliding fit. The tool piece is detachably secured in the cutout by a screw mechanism including an elongated rod supported within and anchored at one end to the handle at a point displaced from the tool piece and which at its other end threadably engages a threaded opening formed in the shank portion of the tool piece.
