Patent attributes
A shaving blade is proposed. The shaving blade includes a substrate having a cutting edge, a substrate tip, and a plurality of coating layers laminated on the substrate. A first thickness of the substrate is defined as a thickness measured at a first distance that is 8 micrometers from the substrate tip along a central axis. A second thickness of the substrate is defined as a thickness measured at a second distance that is 16 micrometers from the substrate tip along the central axis. A third thickness of the substrate is defined as a thickness measured at a third distance that is 32 micrometers from the substrate tip along the central axis. The plurality of coating layers include a first coating layer, a second coating layer, and a third coating layer, and contain one or more of chromium boride (CrB), chromium carbide (CrC), or Diamondlike carbon (DLC).
