RAZOR BLADES

A razor blade (10) having a substrate (11) with a cutting edge being defined by a sharpened tip (12). The substrate has a thickness (21) of between about 1.3 and 1.6 micrometers measured at a distance (20) of four micrometers from the blade tip, a thickness (23) of between about 2.2 and 2.7 micromet...

Summary:A razor blade (10) having a substrate (11) with a cutting edge being defined by a sharpened tip (12). The substrate has a thickness (21) of between about 1.3 and 1.6 micrometers measured at a distance (20) of four micrometers from the blade tip, a thickness (23) of between about 2.2 and 2.7 micrometers measured at a distance (22) of eight micrometers from the blade tip, a thickness (25) of between about 3.8 and 4.9 micrometers measured at a distance (24) 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.
