Abstract
An improved wedge is provided for securing the heads of striking tools such as hammers, axes and the like to the extremities of their elongated wooden handles. The wedge is of monolithic metal construction, having a downwardly directed edge or sufficient sharpness to penetrate wood, and having a centered aperture. When the wedge is driven into the handle, the wood grain expands into the aperture, thereby securing the wedge.
Claims3
A wedge device of monolithic metal construction fabricated from an existing metal washer by grinding a portion to a tapered edge, the resulting wedge device having a circular outer perimeter and circular aperture, and
- an upper extremity of sufficient thickness to resist deformation when hammered upon,
- a lower extremity having a downwardly directed edge of sufficient sharpness to penetrate wood,
- opposed substantially flat boundary surfaces in spaced apart relationship defining the general thickness of the device, and
- said aperture communicating between said boundary surfaces in substantially centered relationship with respect to said perimeter.
