Abstract
(EN)
A shaving apparatus (1) provided with at least one cutting unit (3) comprising an external cutting member (4) and an internal cutting member (5) which is drivable relative to the external cutting member in at least one driving direction P. The internal cutting member comprises at least one cutting element (10) comprising a cutting edge (11) being movable along a cutting path (12) whilst being driven in the at least one driving direction. The external cutting member comprises at least one hair entry aperture (8) which is bounded by at least a first and a second wall portion of the external cutting member at least the first wall portion (13) comprising a cutting edge A for cooperation with the cutting edge of the internal cutting member. An edge portion of the second wall portion (44 54) facing a plane comprising the cutting path in a cross section taken substantially perpendicularly to the plane (22) comprising the cutting path touches a virtual circle (58) with a radius of at least (30) micrometer at at least two contact points (59 60) on the virtual circle and wherein the tangents at two successive contact points where the edge portion touches the virtual circle enclose an angle of at least 150 degrees.
