Zusammenfassung: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.
