Abstract
The various embodiments of the present invention are directed to razor heads having a plurality of cutting edges wherein the physical characteristics of the cutting edges are different from each other. Among the items which may be varied in the blades are the substrate material, coatings or shape. Preferably, the characteristics of the first blade should be such as to maximize the blade's cutting effect in relation to the skin/beard flow over the guard bar of the razor head. The subsequent blades are such as to maximize the cutting action as the skin flow over the first blade and on to the subsequent blades. In addition, one or more fencing elements may be disposed over discrete, spaced portions of one or both cutting edges to prevent those portions of the cutting edges from contacting the skin being shaved.
