Abstract
(EN)

A shaving apparatus is provided having at least one cutting unit comprising an external cutting member and an internal cutting member which is rotatable relative to the external cutting member, the external cutting member being formed with elongate hair-entry apertures, the longitudinal bounding walls of an aperture being substantially parallel. In order to improve the shaving performance the bounding walls of a hair-entry aperture are inclined from the outside towards the inside in the driving direction.
