ABSTRACT:
A method for forming a blade having circular apertures with sharpened edges. As opposed to the traditional grinding and deburring method, the present invention utilizes electrochemical machining, electrical discharge machining, electrolytic machining, laser-beam machining, electron-beam machining, photochemical machining, ultrasonic machining, and other non-traditional methods to sharpen and form the blade edges. These manufacturing methods lend themselves to produce unlimited razor blade designs and structures.
