Claim:
A method of manufacturing razor blades having blade edges from a strip material having a lengthwise-extending blade edge region, the method comprising: (a) contacting a surface of the lengthwise-extending blade edge region with at least one roller to provide a beveled surface at said blade edge region wherein said strip material is moving in a lengthwise direction on a processing line and maintaining a tension on said strip material by having a first tension leveling station before step (a) working with a second tension leveling station after step (a); (b) converting the lengthwise-extending blade edge region of the strip material from step (a) into the razor blade edges; and separating the strip material at approximately the middle of the blade edge region, wherein said beveled surface at said lengthwise-extending blade edge region has a thickness that is less than the thickness of the strip material adjoining the lengthwise-extending blade edge region, to form the blade edges of the razor blades.
