ABSTRACT:
A method for manufacturing an inner cutter for a reciprocating electric shaver, including the steps of: press-stamping a thin metal plate to obtain a thin metal plate element that has an outer contour of an unfolded inner cutter and elongated openings that extend substantially perpendicular to the direction of the reciprocating motion the inner cutter makes and further has bridging-portions formed between the elongated openings; pressing the bridging-portions so that each bridging-portion has a final sectional shape of each cutter blade of the inner cutter; twisting the bridging-portions so that the cutter surfaces of the cutter blades are aligned substantially to the surface of the thin metal plate element; forming the thin metal plate element into substantially an arch shape with the cutter surface sides of the cutter blades facing outward; and executing finishing-work on the outer circumferential surface of the arch-shaped thin metal plate element.
