Abstract
A shaving apparatus having an external cutting member and an internal cutting member, which is rotationally drivable with respect to said external cutting member, which external cutting member is formed with a circular groove having a bottom wall and an upright inner and outer wall, the bottom wall and the outer wall having at least a plurality of slit-shaped hair-entry apertures oriented substantially radially, the inner wall and a small part of the adjoining bottom wall further forming an uninterrupted guard wall which precludes the entry of hairs. To improve the hair-catching performance the guard wall has grooves which are oriented substantially radially and which are disposed in line with the slit-shaped hair-entry apertures.
