  • Publication number: 20010015017
    Abstract: The invention relates to a shaving head (5) comprising a cutting member (17) and a hair manipulator (23). The cutting member comprises a cutting edge (19) which extends in a direction (X) perpendicular to a shaving direction (Y) of the shaving head. The hair manipulator is arranged in front of the cutting edge, seen in the shaving direction, and can be driven in a direction parallel to the cutting edge. Hairs trapped by the hair manipulator are moved along the cutting edge while being cut, so that the cutting forces in the shaving direction are reduced.
