Abstract: A razor blade with an asymmetric substrate. A non-fluorinated organic coating extending along a first and second outer sides of the asymmetric substrate from a tip region toward a base of the substrate.

Abstract: A razor blade with a sharpened cutting edge with an outer bonding surface. A non-fluorinated organic coating material deposited on the outer bonding surface forming an outermost layer of the sharpened cutting edge. The non-fluorinated organic coating is composed of one or more self-assembled monolayers.

Abstract: A razor blade with a substrate having a tip portion. A hard coating layer is deposited on the substrate. A non-fluorinated organic material is deposited in one or more monolayers on an outer bonding surface of the hard coating. The hard coating layer has an aspect ratio of (a) to (b) of at least 1.5:1, wherein (a) is a first distance from a tip defined by the hard coating layer to the tip portion of the substrate, and (b) is a second distance from an outer surface of the hard coating layer to an underlying surface of the substrate.

Abstract: A method of making a razor blade by forming a cutting edge on a substrate having an outer bonding surface. A first self-assembled monolayer having a non-fluorinated organic material is deposited on the outer bonding surface of the substrate.

Abstract: A razor blade having a substrate with a cutting edge being defined by a sharpened tip and novel dimensions is provided. The substrate has dimensions of volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The substrate is coated with one or more materials and has novel volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The thickness of the substrate at 2 micrometers back from the ultimate tip is at or below about 0.977 micrometers and at or below about 1.173 micrometers for a coated substrate at the same distance. These dimensional values are measured robustly with an atomic force microscope and provide reduced cut forces for improved blade performance.
