Abstract
A shaving apparatus has at least one cutting unit (3) comprising an external cutting member (4) and an internal cutting member (5) which is drivable relative thereto, which external cutting member (5) has a number of broad and narrow hair-entry apertures (7a, 7b) which are bounded by peripheral portions (12, 13) of the external cutting member. In order to enable both short and long hairs to be caught and severed effectively while irritation of the skin is avoided as far as possible, the peripheral portions (12, 13) bounding the hair-entry apertures (7a, 7b) have different thicknesses, the width (B1) of a hair-entry aperture (7a) between two thick peripheral portions (12) being greater than the width (B2) of a hair-entry aperture (7b) between two thin peripheral portions (13).
