  • RAZOR BLADE
    Publication number: 20220105648
    Abstract: A razor blade including a substrate with a cutting edge portion ending in a sharpened tip. The substrate having a thickness of between 1.55 and 1.97 micrometers measured at a distance of five micrometers from the tip, a thickness of between 4.6 and 6.34 micrometers measured at a distance of twenty micrometers from the tip, and a thickness of between 19.8 and 27.12 micrometers measured at a distance of one hundred micrometers from the tip.
    Type: Application

  • Razor blade
    Patent number: 11090826
    Abstract: A razor blade comprising a blade substrate with a blade edge substrate portion ending in blade tip. The razor blade is covered by a strengthening coating deposited on the blade edge substrate portion via a deposition process. The deposition process causes a hardness value of the strengthening coating layer to be increased, which, among other factors, allows for a decreased thickness of the blade substrate with coating. The blade substrate with coating has (i) a thickness of between about 1.57 and 2.37 micrometers measured at a distance of about five micrometers from the coating tip, (ii) a thickness of between about 4.62 and 6.74 micrometers measured at a distance of about twenty micrometers from the coating tip, and (iii) a thickness of between about 19.82 and 27.52 micrometers measured at a distance of about one hundred micrometers from the coating tip.
