摘要： A razor blade has a symmetrical tapering blade edge ending in a blade tip. The razor blade includes a substrate and a coating covering the substrate. The coating includes a soft coating and a hard coating. The hard coating includes at least a main layer. The soft coating covers the hard coating. The substrate has a substrate tip including a tapering geometry toward the substrate tip. The substrate tip has specific thicknesses at distances of 5 micrometers, 20 micrometers, 40 micrometers, and 200 micrometers from the substrate tip.
