摘要： A razor cartridge is provided comprising: a housing and a blade assembly mounted to the housing. The blade assembly may comprise at least one razor blade defined by a substrate comprising a first portion and a second portion. The first portion may comprise first and second outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet and an end facet. The second section may comprise an end facet. The end facets of the first and second sections may converge at a tip to define a cutting edge. A shoulder may be positioned between the first facet and the end facet of the first section and define a skin-contacting surface.

摘要： A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has a thickness of greater than about 2.30 micrometers measured at a distance of four micrometers from the blade tip, a thickness of greater than about 4.26 micrometers measured at a distance of eight micrometers from the blade tip, and greater than about 7.93 micrometers measured at a distance of sixteen micrometers from the blade tip. A hard coating joined to the substrate has a thickness of 700 Angstroms to about 3500 Angstroms. An outer layer joined to a coated substrate is discontinuous. The outer layer may be produced from a dispersion comprising about 0.03g/L or less of telomer or from about 0.5% solids or less of telomer by weight of composition. The novel razor blade cuts at less than 100% cutting efficiency using a single fiber cutting efficiency measure.
摘要翻译：具有基底的剃刀刀片具有由尖锐尖端限定的切割边缘。在距离叶尖4微米的距离处测量的基材具有大于约2.30微米的厚度，在距离叶片尖端8微米的距离处测得的厚度大于约4.26微米，并且测得的所述厚度大于约7.93微米距离叶尖16微米的距离。连接到衬底的硬涂层具有700埃至3500埃的厚度。连接到涂覆基底的外层是不连续的。外层可以由包含约0.03g / L或更少的调聚物或约0.5％固体或更少的组合物重量的调聚物的分散体生产。采用单根纤维切割效率测量，新型刀片的切割效率低于100％。

摘要： A razor blade is provided comprising a substrate comprising a first portion and a second portion. The first portion may comprise first and second generally parallel outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet extending directly from the first outer surface of the first portion and an end facet extending directly from the first facet. The second section may comprise an end facet. The end facets of the first and second sections may converge at a tip to define a cutting edge. The split line may pass through the tip and is generally parallel with and extends between the first and second outer surfaces of the first portion.

摘要： A razor blade having a substrate with a cutting edge being defined by a sharpened tip is provided where the substrate is comprised of a molybdenum (Mo) content of about 1.6% to about 5% by weight of composition and thicknesses of 1.60-1.75µm and 9.25-10.00µm measured at a distance of 4 and 40µm from the blade tip, respectively. This thickness ratio is between 0.165-0.185. The substrate thickness is about 2.70-3.00µm at 8µm from the blade tip, about 4.44-5.00 µm at 16µm from the blade tip with a thickness ratio measured at 4µm and 8µm between 0.56-0.62, and a thickness ratio measured at 4µm and 16µm between 0.32-0.40. The edge shape may be defined by equation w=ad n with "a" between 0.50-0.62 and "n" between 0.76-0.80. A semi-included angle less than 7 is measured at a distance of 40µm or greater from the blade tip. This substrate will have substantially no cracks.
