ABSTRACT:
An elongate unitary splitting device having a lower portion of multiangular configuration with a pair of opposed edges converging at a first angle toward a pointed lower end. An upper portion additionally has a pair of oppositely facing, generally planar side surfaces which intersect and extend upwardly from said edges. The angle between the side surfaces is at least as great as the angle of convergence of the opposed edges. A spear-point configuration provided by the lower end produces ease of startup penetration, and the upper portion produces efficient splitting once initial penetration has occurred.
