ABSTRACT:
A visual wear indicator which may incorporate a shaving aid, such that the visual wear indicator corresponds to released shaving agents, wear or oxidation of a cutting edge. The visual wear indicator may include a shaving aid composite which exhibits a first color to the user during an initial use and a different color during a subsequent use, wherein the transition from the first color to the second color is designed to correspond to a predetermined parameter of the shaver. The visual wear indicator may also include a metallic surface having an oxidation rate which parallels the oxidation rate of a cutting edge and provides a sufficient surface area to exhibit a second color upon detrimental oxidation of the blade.
