发明名称 Tool wedge
摘要 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.
