    Abstract: An electric shaving apparatus has a housing serving as a hand grip (1) with projecting support lugs (11, 12) that defines pivot axis (Z). Shearing head system (2) is movable about pivot axis (Z) and comprises a shearing head frame (3) that has at least one upper cutter (4) with arcuate extensions towards the longitudinal sides (5, 6) of the shearing head frame (3), and at least one under cutter (25, 26, 34) driven by a motor and in cooperative relation with the upper cutter (4).
