  • CUTTER BLADE ASSEMBLY AND DRY SHAVER FOR VARIABLE HEIGHT OF CUT
    Publication number: 20170021512
    Abstract: A dry shaver unit includes a housing and a cutter blade assembly mounted in the housing. The cutter blade assembly includes a cutter blade and cooperating shear blade arrangement. The thickness of the shear blade varies over its surface, such that the spacing between a portion of the skin engaging surface of the shear blade and the opposite face thereof is increased as compared with the spacing required to achieve a “close shave”. The cutter blade assembly is mounted in the housing such that a plurality of portions of the shear blade having different thicknesses are simultaneously available for application to a surface to be shaved.
