Rasiersystem mit Klingenverschleissanzeiger

The present invention is directed to a wet shaving system having an electronic indicator for indicating when the blades are becoming dull and in need of replacement. As razor blades dull, the user must exert greater force during shaving to achieve a satisfactory shave. Upon exertion of this extra force, a piston (12) which is adjacent to the blades moves away from the blades in response to the increased forces encountered by the blades during shaving. Upon moving a sufficient distance, the piston pushes into an electronic device, such as a potentiometer (20), which initiates a signal processing circuit (15) which in turn activates an indicator, such as a light-emitting diode. The activation of the indicator is a signal to the user to replace the blades.
