Abstract
Disclosed is a shaving apparatus having a shear plate provided with hair-entry apertures and a cutting member drivable relative to the shear plate. The cutting member is formed with cutters each having an associated lead cutter slidingly engaging the guide wall of its respective cutter. The end of each lead cutter has a projection terminating in a cutting edge for penetration into a hair, the thickness of such projection permitting only partial penetration of the lead cutter into the hair. Such penetration is advantageously further limited by forming the front wall of the lead cutter perpendicular to the end wall of its associated cutter.
