Abstract: A method of manufacturing a razor cartridge by providing a blade unit having a first side wall, a second side wall, and a pair of end walls interconnecting the first side wall and the second side wall. A plurality of blades are secured to the blade unit with a clip positioned at each end of the blade unit adjacent to one of the end walls. Each blade has a blade edge contacting a bottom surface of each of the clips. A frame is provided having a first interior wall and a second interior wall spaced apart from first interior wall that define an opening extending completely through the frame. The blade unit is positioned within the opening of a frame after securing the blades to the blade unit, such that the frame surrounds the blade unit. The blade unit is secured to the frame.

Abstract: A method of manufacturing razor blades from a strip material includes reducing the thickness of a lengthwise-extending blade edge region of the strip material.

Abstract: Connecting structures are provided, for connecting a cartridge to a handle in a shaving razor, e.g., a razor for wet shaving. A cartridge connecting a structure includes a molded body, and a blade unit receiving portion having a shell bearing structure that pivotally receives a blade unit, the shell bearing structure comprising a pair of shell bearings. The cartridge connecting structure further includes a spring return for biasing the blade unit relative to the cartridge connecting structure, the spring return being positioned between the shell bearings and extending integrally from the molded body of the cartridge connecting structure.
