Publication number: 20230347537Abstract: A razor blade having a substrate with a cutting edge being defined by a sharpened tip and novel dimensions is provided. The substrate has dimensions of volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The substrate is coated with one or more materials and has novel volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The thickness of the substrate at 2 micrometers back from the ultimate tip is at or below about 0.977 micrometers and at or below about 1.173 micrometers for a coated substrate at the same distance. These dimensional values are measured robustly with an atomic force microscope and provide reduced cut forces for improved blade performance.Type: ApplicationFiled: March 21, 2023Publication date: November 2, 2023Inventors: John Lawrence Maziarz, Michael Joseph Baxter, Jonathan Raymond Petrie, Oliver Heinz Claus

Patent number: 10625331Abstract: 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.Type: GrantFiled: October 16, 2017Date of Patent: April 21, 2020Assignee: The Gillette Company LLCInventors: Wei Han, Ming Laura Xu, John Lawrence Maziarz
