  • Patent number: 5075969
    Abstract: A shower shaver is made from two plastic piece parts. A first part is a handle in the nature of a pipe terminating in a fan-shaped or flared, tray like top surface. The other piece part is a cover or top which fits over and cooperates with the tray top to form a cavity which delivers a flared sheet of water toward orifices which cause the water to strike to a broad surfaces of said blade and then exits under the cutting edge of the blade with enough force to wash debris away from the blade. A notch beneath the flaired surface delivers a stream of water to the skin in advance of the cutting edge. A tubing or hose attached to the shower shaver razor leads to a nipple which may be interposed between a shower head and a plumbing pipe. A valve on the nipple provides a continuously variable control over the flow of water to the shaver and/or the shower head.
