  • Publication number: 20230074295
    Abstract: A cutting mechanism for a hair cutting apparatus, such as a shaving apparatus, includes an outer cutting member having hair-entry openings and an inner cutting member having cutting elements each having a first cutting edge. The inner cutting member is moveable with respect to the outer cutting member so as to perform a cutting operation within a cutting region of the cutting mechanism. Adjacent hair-entry openings are separated by a dividing element having a cutting section that lies within the cutting region and a non-cutting section that is outside the cutting region. The non-cutting section includes an inner wall facing the inner cutting member and a side wall which is substantially perpendicular to the inner wall. A single chamfer is provided between the inner wall of the non-cutting region and the side wall of the non-cutting region.
