Provided is a razor blade material has excellent high hardness, high strength and high corrosion resistance. The material is made of an Fe-base alloy containing, by mass %, 0.5 to 5.0% carbon, 9.0 to 14.0% Cr and 0.5 to 8.0% Mo. The material includes precipitates which can be observed at an optional sectional surface of the razor blade material and each of which has a diameter of less than 0.1 mum. The alloy has preferably a chemical composition of 0.5 to 5.0% carbon, 9.0 to 14.0% Cr and 0.5 to 8.0% Mo, 0.5 to 8.0% of B+Si, and the balance of Fe and unavoidable impurities. Preferably, the alloy material has a metal structure, not less than 30 volume % of which is amorphous. The material has a thickness of 30 to 100 mum. The material is preferably coated with polytetrafluoroethylene (PTFE).
