ABSTRACT:
An inner cutter for electric shavers is disclosed. The inner cutter comprises a plurality of inner blades mounted on a base member to be driven to move in sliding engagement with an outer shearing plate having a number of perforations therein. Each inner blade has along its length the cutting edge of different configurations including at least a toothed edge so as to define a first cutting edge of a greater overall width determined by the amount of projection of the tooth in the direction of movement of the inner blade and a second cutting edge in the form of a straight edge or toothed edge of an overall width less than that of the first cutting edge. The first cutting edge is responsible for efficiently capturing and cutting long hairs into shorter ones, while the second cutting edge is for giving a close shave on the skin of a user. Accordingly, the long hairs can receive two different cutting operations at each inner blade so as to be in a close cut after being successfully captured. In such a manner, the above unique edge configuration enables the efficient cutting operation for both long and short hairs.
