Abstract
A shaving apparatus has a circular shear plate provided with hair-entry apertures and a cutting unit associated with and rotatable relative to the shear plate. The cutting unit comprises a cutting member having a circular central body provided with circumferentially arranged cutters and lead cutters respectively associated with and movable relative to the cutters. Each lead cutter is secured to the central body of the cutting member by a resilient connecting arm, the inner end portion of which extends substantially radially with respect to the cutting unit axis and undergoes torsion-loading by reason of the movement of the lead cutter away from the shear plate, the lead cutter being connected eccentrically to such inner end portion. The torsion-loading is elastically opposed in each instance.
