An earth splitting tool comprised of a central shaft, a handle bar, a foot pressure bar and a wedge-shaped blade is disclosed. The blade has two primary trapezoid-shaped faces, two triangular side faces and a rectangular butt face. One primary face in the same plane as a tangent to the surface of the central shaft. The butt face has a width substantially the same as the thickness of the central shaft. The butt face may be perpendicular to the axis of the central shaft, or it may be sloped away from the perpendicular. The length of the butt face may also be substantially the same as the thickness of the central shaft.
