Abstract

A trimmer for dry shavers having cutting screen mounted integral with the appliance and a cutter movable reciprocally along said cutting screen, formed of a cutter blade and a support. The support of the cutter is manufactured by the injection-molding technique and the cutter blade is injection-molded onto it when manufactured. Recesses of different shapes with central constrictions are provided in the cutter blade to receive the support material, said constrictions, despite the shrinkage of the support material, ensuring a secure zero-play material connection between the support and the cutter blade.
