Abstract

See full text

A method of manufacturing a razor blade by providing a razor blank strip having an edge. The razor blank strip is hardened to a hardness greater than 600HV. A pre-bending zone that is spaced apart from an edge of the razor blank is melted with a laser beam. The pre-bending zone is cooled after melting to form a re-solidification portion. The razor blank strip is segmented into individual blades. The individual blades are bent in the pre-bending zone.
