Abstract

The invention is directed to a long-hair cutter unit (LHS) for a dry shaving apparatus (TR), with a dimensionally stable cutting comb (11) having one cutting teeth row (17) and at least one bearing surface (110) for at least one engagement surface (120) of an arcuately curved, hardened cutting blade (12) having one cutting teeth row (18) and held in engagement with the cutting comb (11) by a pressure of at least one spring element (19, wherein the curvature of the hardened cutting blade (12) is partially configured by means of a forming process such as to ensure conformance and slidable contact of the engagement surface (120) of the cutting blade (12) with the bearing surface (110) of the cutting comb (11) by means of the partial curvatures as well as their restoring forces under the action of the pressure of the spring element (19).
