Abstract: A shaving head that doubles as breaking mechanism to break a safety razor blade into two pieces to form a 2-blade shaving razor. The shaving head includes a front component having a retention guide, a first position stop and a second position stop at a distance offset from the first position stop. The shaving head further includes a back component having a blade slot configured to receive a first blade portion and a second blade portion formed from breaking a double-edge safety razor blade such that the first blade portion has a different width compared to the second blade portion. The retention guide is configured to retain the first blade portion and the second blade portion in the blade slot responsive to the retention guide being at least partially inserted into the blade slot. The sharp shaving edges once installed form a shaving angle between 5 and 30 degrees, where the shaving angle is determined by where the blade is broken.

Abstract: 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.

Abstract: Counter-reliefs of faces of blanks of blades are machined in flat stock sheets of steel with a precision provided by the machining and without producing thermal damage (i.e., overheating) and/or chatter marks on the surface of the blanks of the blades. The blanks of the blades are separated from the flat stock sheet of steel and quickly and easily finished to a quality equal to a quality of handmade cottage industry blades.

Abstract: A method and apparatus are provided for attaching a safety cutting blade onto a substrate, such as a cardboard blank. A piece of cutting blade material is cut to length and fed to a forming station that bends the piece to form a safety cutting blade having a plurality of cutting teeth. The cutting blade is fed to a crimping station where the cutting blade is mated with a substrate and affixed with the substrate. A transport then conveys the combined cutting blade and substrate away from the crimping station.
