The method involves removing material from a reprocessed die (16) and changing a location of a cutting edge of the die to a punch entry direction. A punch and a metal sheet thickness are assigned to the reprocessed die based on the change in the cutting edge cross-section of the reprocessed die. Independent claims are included for the following: (1) reprocessed die; (2) punch machine; and (3) computer readable medium storing program for reprocessing die.
