The invention relates to a cutting member ( 7 ) for use in a device for shaving hair. The cutting member comprises a steel substrate ( 15 ) which is provided with a cutting edge ( 9 ). At least a portion of a surface ( 27 ) of the substrate including the cutting edge is provided with a protective coating ( 19 ) having a hardness which is higher than a~hardness of the steel substrate. According to the invention, the portion of the surface ( 27 ) of the substrate ( 15 ) provided with the coating ( 19 ) is nitride hardened. As a result, the substrate provides an improved mechanical supporting function for the coating. In this manner, the risk that the coating will break as a result of deformations of the substrate, which occur under', the influence of high mechanical loads on the coating and on the cutting edge ( 9 ), is considerably limited. Examples of suitable coatings ( 19 ) in combination with the nitride (hardened steel substrate ( 15 ) are diamond-Like carbon and coatings having a superlattice structure comprising carbon and a metal, e.g. Cr.
