An improved wood splitting maul wherein the striking edge is at an improved angle. The improved angle makes the maul easier to use, more efficient, and provides less shock to a user's body. The improved angle is defined by a straight line essentially running along the length of the splitting edge (or hammer face) to a point at a pivot point defined between about the bottom end of the handle where the maul is grasped while in use and the approximate location of the elbow of the user of the maul and a line along the longitudinal axis of the handle. The exact degree or the absolute optimum value of the angle is a function of the handle length, the distance of the splitting edge (or hammer face) from the handle axis and the size of the user of the maul. The efficiency is improved to such a degree that a handle of only 28 inches in length provides improved performance in the manual splitting of wood.
In an improved wood splitting maul head unit having an aperture therethrough configured for attaching a handle of predetermined length, said handle having a head end and a bottom end, said wood splitting maul head unit having incorporated thereon one wood splitting edge said improvement comprising:
In an improved wood splitting maul with a head unit having a wall means defining a handle attaching aperture therethrough, and a handle unit of predetermined length attached to said head unit at a head end of said handle unit, said head unit having incorporated thereon a striking face and a wood splitting edge, said improvement comprising:
In an improved wood splitting maul with a head unit having a wall means defining a handle attaching aperture therethrough, and a handle unit of predetermined length attached to said head unit at a head end of said handle unit, said head unit having incorporated thereon two striking faces one of said two striking faces is a splitting edge and a second striking face is a hammer face, said improvement comprising:
