ABSTRACT:
An inner cutter for a dry shaver is fabricated from a metal plate to have a plurality of blades each provided with cutting edges. The metal plate includes a plurality of parallel straight slits to leave an array of straight beams each defined between the adjacent ones of the slits. The beams are forged and ground at a segment of each beam to give the cutting edges thereto. After making the cutting edges, the metal plate is bent into a generally U-shaped configuration so as to correspondingly curve the beams and shape the beams into the blades having the arcuate contour and the cutting edges. The metal plate is provided with a joint for connection with a driving source of moving the inner cutter relative to an outer cutter.
