ABSTRACT:
An ergonomic, improved multiple bit storing hand tool that provides storage capacity for a large number of bits while minimizing bulk material volume and hand gripping member cross sectional area so as to provide for increased gripping ability. The improved multiple bit storing hand tool includes a non-cylindrical, elongated, hand gripping portion having corners and a central axis substantially parallel to a plurality of substantially parallel corner axes of the corners. In a variant, the corner axes are generally lobular and include epicycloidal portions thereof. Each of the substantially parallel corner axes are substantially equidistant from the central axis and substantially equidistant one from another. A plurality of elongated storage compartments having compartment axes are substantially parallel to the parallel corner axes and the central axis. A plurality of the elongated storage compartment axes are substantially disposed at a point on an imaginary line connecting the central axis and each of the parallel corner axes. The number of bits stored within the multiple bit storing hand tool is maximized while the elongated hand gripping portion of the hand tool is minimized in bulk volume and weight as compared to a conventional tool having a cylindrical hand gripping portion.
