摘要： The knife of the present disclosure includes a blade having a first side face and a second side face. The blade includes zirconia as a main component, and includes a cutting region including at least a ridge portion between the first side face and the second side face. When a portion including the cutting region in the first side face is referred to as a first cutting face, and a portion including the cutting region in the second side face is referred to as a second cutting face, the proportion of cubic crystals of zirconia in the first cutting face is larger than the proportion of cubic crystals of zirconia in the second cutting face.

摘要： A composite utility knife blade and method of making such a blade involves butt joining a tool steel wire (44) to a front edge of an alloy steel backing strip (34). The wire (44) is electron beam welded to the backing strip (34) to form a composite strip defining a first metal portion (20) formed by the alloy steel backing strip (34), a second metal portion (22) formed by the tool steel wire (44), and a weld region (28) joining the first and second metal portions. The composite strip is then annealed, and the annealed strip is straightened to eliminate any camber therein. The annealed composite strip is then hardened such that the first metal portion defines a surface hardness within the range of approximately 38 Rc to approximately 52 Rc, and the second metal portion defines a surface hardness within the range of approximately 60 Rc to approximately 75 Rc. The hardened strip is then subjected to at least two tempering and quenching cycles. Then, facets are formed on the edge of the second metal portion to form a straight, tool steel cutting edge along at least one side of the composite strip. The composite strip is then scored at axially spaced locations to form a plurality of score lines, wherein each score line is oriented at an acute angle relative to the axis of the strip, and the plurality of score lines define a plurality of blade sections and scrap sections located between the blade sections. Each scrap section is bent outwardly relative to a plane of the composite strip on one side of a respective scorn line, the composite strip is then pressed on an opposite side of the respective score line, and the respective blade section is then snapped away from the bent scrap section along the respective score line.

摘要： In a vacuum chamber, the edge of each blade group is subjected to an ion beam treatment under predetermined conditions using a plasma ion gun and argon as a medium, and is subjected to a plasma ion implantation of nitrogen plasma under predetermined conditions using a plasma ion implantation gun. As a result, it is possible to provide a blade member having an edge of a cutting quality enhanced by increasing the sharpness, a blade member having an edge of a rigidity enhanced by increasing the hardness, and a working apparatus capable of working those edges efficiently.

摘要： A blade made of a carbon steel or alloy steel is subjected to a surface nitriding process to form a high hardness nitride layer having a thickness in the range of 10 µm to 100 µm and a Vickers hardness Hv of 1000 or more, and a silver oxide layer, a copper oxide layer, or a silver oxide and copper oxide layer is formed on the high hardness nitride layer of the blade by firing. Through this processing, the blade that has a high cutting maintaining ability and an excellent sanitization ability such as antibiosis, sterilization ability, and antimold ability is provided.

摘要： A process for manufacturing an obturator blade for a surgical obturator includes the steps of providing an obturator blade blank, pressing the blade blank to form intersecting surfaces adjacent one side, preferably, both sides, of the blade blank and forming a cutting edge adjacent an area of intersection of the intersecting surfaces to thereby form an obturator blade for incorporation in a surgical obturator. The step of pressing preferably includes the step of coining the blade blank with at least one coining die to, e.g., form at least one arcuate surface adjacent the one side of the blade blank. The at least one arcuate surface is one of the intersecting surfaces. More preferably, the step of coining includes forming arcuate intersecting surfaces adjacent the-one side of the blade blank. The arcuate intersecting surfaces may be substantially concave intersecting surfaces. Alternatively, the step of coining includes forming substantially planar intersecting surfaces adjacent the one side of the blade blank.
