发明名称 Wood splitting maul
摘要 A maul head for a wood splitting maul includes a raised ear disposed centrally on each side face of the head. The ears are of a substantially smaller width than the side faces of the maul head and are configured to provide a wedge shaped entry portion which is spaced from the cutting edge of the side faces. The distance between the outer faces of the ears progressively increases from the leading edge to the trailing edge of the ears. The ears provide an increased splitting action after the initial penetration of the cutting edge.
