Claims22
A method of manufacturing razor blades including blade edges from a strip material having a lengthwise-extending blade edge region that is converted to the blade edges during the method, the method comprising
- (a) pressing a portion of the lengthwise-extending blade edge region to provide the portion with a thickness that is less than the thickness of the strip material adjoining the lengthwise-extending blade edge region, and
- (b) converting the strip material from step (a) into the razor blades including the blade edges.
A method of manufacturing razor blades having blade edges from a strip material having a lengthwise-extending blade edge region that is converted to the blade edges during the method, the method comprising:
- (a) contacting a surface of the lengthwise-extending blade edge region with at least one roller to provide a beveled surface, and
- (b) converting the strip material from step (a) into the razor blades including the blade edges.
A method of manufacturing razor blades, comprising
- converting a strip material including a lengthwise-extending blade edge region that subsequently becomes blade edges on the razor blades and has a thickness that is less than the thickness of the strip material adjoining the lengthwise-extending blade edge region into razor blades including the blade edges.
