Abstract: The present invention provides a steel strip for cutlery, which has a composition containing, in mass %, 0.45 to 0.55% of C, 0.2 to 1.0% of Si, 0.2 to 1.0% of Mn, and 12 to 14% of Cr, and further contains Mo, with the balance made up of Fe and unavoidable impurities, in which Mo is contained in an amount of 2.1 to 2.8%, and the amount of formed M3C deposited by tempering is decreased to improve bending workability.

Abstract: The present invention provides a razor blade steel and method of forming a razor blade from a steel which has a high hardness but is also ductile after being subjected to a heat treatment and bending process. The novel razor blade steel has Molybdenum (Mo) content of between about 1.6% to about 5% in weight percent of composition. The razor blade comprises substantially no tempered carbide, tempered carbide of about 0.1 ?m or smaller, and substantially no cracks in a bent portion. One embodiment of the novel razor blade steel has a composition comprising, in weight percent, about 0.45% to about 0.55% of C, about 0.4% to about 1.0% of Si, about 0.5% to about 1.0% of Mn, and about 12% to about 14% of Cr, and further includes Mo in an amount of about 2.1% to about 2.8%.

Abstract: A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has a thickness of between about 1.3 and 1.6 micrometers measured at a distance of four micrometers from the blade tip, a thickness of between about 2.2 and 2.7 micrometers measured at a distance of eight micrometers from the blade tip, a thickness of between about 3.8 and 4.9 micrometers measured at a distance of sixteen micrometers from the blade tip, a ratio of thickness measured at four micrometers from the blade tip to the thickness measured at eight micrometers from the blade tip of at least 0.55 and a ratio of thickness measured at four micrometers from the blade tip to the thickness measured at sixteen micrometers from the blade tip of at least 0.30.
