Abstract
A shaving assembly is provided with skin-flow control means positioned in advance of the blade edge to control the effective exposure and blade-to-skin angle of the blade edge so as to greatly minimize or eliminate nicking. The skin-flow control means serves to minimize or eliminate the skin bulges which may otherwise be created in the unsupported space between a razor guard element and the blade edge. The skin-flow control means is provided by extending the skin-supporting surface of the guard element into such close proximity with the blade edge that the formation of a skin bulge therebetween is substantially prevented. A plurality of small holes may be provided in the guard element near the blade edge for allowing water flow therethrough to rinse shaving debris from the region of the blade.
