摘要： A method of manufacturing a razor blade by providing a razor blank strip 32 having an edge 34. The razor blank strip is hardened to a hardness greater than 600HV. A pre-bending zone 42 that is spaced apart from an edge of the razor blank is melted with a laser beam 38. The pre-bending zone is cooled after melting to form a re-solidification portion 30. The razor blank strip is segmented into individual blades. The individual blades are bent in the pre-bending zone.

摘要： Razor blades with two or more materials and/or methods of fabricating the same. In one example, a bimetal razor blade can comprise a blade body and a blade edge. The blade body can have a length and a width. The blade body can be formed of a first substrate portion comprising a first material having a first hardness. The blade edge can extend along the length. The blade edge can be formed of a second substrate portion coupled to the first substrate portion. The second substrate portion can comprise a second material having a second hardness that is distinct from the first hardness. The first and second materials can be metals.

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.
摘要翻译：提供了一种剃刀片，其具有由尖锐尖端限定的切割边缘的基底，其中基底由钼（Mo）含量按组合物重量计约1.6％至约5％的钼（Mo）厚度分别为1.60-1.75微米和9.25-10.00微米，距离叶尖4和40微米。该厚度比在0.165-0.185之间。在叶尖8微米处，基板厚度约为2.70-3.00微米，在距离叶尖16微米处约为4.44-5.00微米，在4微米和8微米之间测得的厚度比为0.56微米 -0.62，在4微米和16微米之间测得的厚度比在0.32-0.40之间。边缘形状可以通过等式w = ad 来定义，其中“a” 在0.50-0.62之间，“n” 在0.76-0.80之间。在距叶尖40微米或更大的距离处测量小于7的半夹角。这种基材基本上没有裂纹。

摘要： The present invention provides a razor blade steel and method of forming a razor blade from a steel which has a high hardness but is also ductile after being subjected to a heat treatment and bending process. The novel razor blade steel has Molybdenum (Mo) content of between about 1.6% to about 5% in weight percent of composition. The razor blade comprises substantially no tempered carbide, tempered carbide of about 0.1 µm or smaller, and substantially no cracks in a bent portion. One embodiment of the novel razor blade steel has a composition comprising, in weight percent, about 0.45% to about 0.55% of C, about 0.4% to about 1.0% of Si, about 0.5% to about 1.0% of Mn, and about 12% to about 14% of Cr, and further includes Mo in an amount of about 2.1% to about 2.8%.
