Abstract:
The present invention arose as a result of the absence in prior art of a means of producing an oscillating motion of the cutter foils in an electric shaver with rotary cutting heads that are in planetary motion. In current practice the cutter foils are stationary when the cutters are rotating. In the present invention the cutter foils can be engaged to oscillate when the cutters are rotating and can be disengaged to use the shaver in the conventional manner.
