  • Patent number: 4773286
    Abstract: Striking tools, heads and handles for such tools, and methods of manufacturing them. A tool head according to this invention employs a flange which extends from each side of the head between the forward and rear portions of the head. The portion of the head within the periphery of each flange is generally concave and narrows to form a web extending longitudinally in the striking direction to connect the forward and rear portions. The web may include at least one opening communicating between the two concave surfaces. The flanges increase the cross-sectional area and moment of inertia of the head relative to the striking direction and relative to the handle axis. The resulting head enjoys greater strength and resistance to translational forces, bending moments, deformation and potential failure. Portions of the handle extending through the opening in the head and thereby about portions of the head reduce the possibility that the head will leave the handle as the tool is being swung.
