Abstract
A shaving system for use with mechanical hand-held shavers includes a housing in which is disposed a DC motor, an eccentric weight coupled to a shaft of the motor, and a DC power source. The eccentric weight and motor shaft are oriented such that the axis of vibrations produced by the motor are parallel to an axis of the cutting edge of a razor blade attached to a handle in mechanical vibratory communication with the motor. The result is vibratory displacement of the razor blade, typically back-and-forth, over a range approximating the dimension of a human hair. In one embodiment a housing accepts the handle of a generic shaver, and in a second embodiment the housing is bifurcated and the handle of a shaver.
