Abstract
A material penetrating tool includes a shaft portion defining a central axis, and an enlarged cutting portion extending downwardly axially from the shaft portion. The enlarged cutting portion includes a rearward blunt surface, a front cutting surface, a first side surface and a second side surface, and the first side surface and the second side surface define an angle of extension measured in a plane perpendicular to the central axis, forming a wider forward cutting surface than the rearward blunt surface in a plane perpendicular to the central axis.
