Abstract: In accordance with the present invention, a plurality of circular shaped, slotted foils or cutting heads are simultaneously produced using electroforming production techniques followed by passage of each slotted foil or cutting head through either a single die or a progressive die to form the slotted foil or cutting head into the desired three-dimensional circular or annular shape required for a rotary shaver. Furthermore, in order to produce a slotted foil or cutting head which is extremely thin, to attain a close, comfortable shave, each of the fully formed slotted foils or cutting heads is passed through an insert molding operation, wherein a supporting rim or ring is affixed to the outer edge of the slotted foil or cutting head, thereby imparting rigidity or stiffness thereto. As a result, slotted foils or cutting head are able to be manufactured at a substantially reduced cost, and with precisely desired and controlled configurations.
