Abstract: A folding hand tool set having a one-piece, completely integral, plastic handle and a plurality of hand tools rotatably mounted thereto. The one-piece, completely integral, plastic handle is preferably constructed from a fiber reinforced thermoplastic. Spacers may be provided for rotationally isolating the hand tools. The folding hand tool set is capable of transmitting more then 110.0 Newton meters of torque without compromising the integrity of the one-piece, completely integral plastic handle. A one-piece, completely integral, plastic handle for receiving hand tools is also disclosed. The handle can withstand at least 30 Newton meters of torsional force without compromising the integrity of the handle.

Abstract: A folding hand tool set having a one-piece, completely integral, plastic handle and a plurality of hand tools rotatably mounted thereto. The one-piece, completely integral, plastic handle is preferably constructed from a fiber reinforced thermoplastic. In one embodiment, spacers are provided for mechanically isolating the hand tools. The folding hand tool set is capable of transmitting more then 110.0 Newton.multidot.meters of torque without compromising the integrity of the one-piece, completely integral plastic handle. The present invention is also directed to a one-piece, completely integral, plastic handle for receiving hand tools. The handle can withstand at least 30 Newton.multidot.meters of torsional force without compromising the integrity of the handle.

Abstract: A drive element for use with TORX.sup..RTM. compatible fasteners with an elliptical cross-section attached to an elongated shaft along the central longitudinal axis of the shaft. The minor axis of the ellipse extends along the central longitudinal axis of the elongated shaft. The elliptical cross-sections of the drive element are located on planes which pass through the minor axis. A major axis plane perpendicular to the minor axis is located at the center of the drive element. The drive element has elevations forming drive lobes and depressions which traverse a longitudinal elliptical path on the surface of the drive element. The lobes and depressions are substantially complimentary to the inner surface of a fastener cavity at the major axis plane. Starting at the major axis plane, the lobes become narrower as they approach the minor axis. The centers of curvature for the tops of the lobes are a series of points which define a first reference circle on the major axis plane with the minor axis as the center.
