Abstract
A punch pin cutting edge configuration having a leading edge and a following edge is described. The leading edge engages a workpiece, such as paper, before the following edge. The following edge is at a steeper angle than the leading edge relative to the workpiece being punched. The cutting edge thus produced reduces the force necessary to punch through the workpiece.
