摘要： A method for manufacturing surgical blades (2402) from either a crystalline or poly-crystalline material, preferably in the form of a wafer (202), is disclosed. The method includes preparing the crystalline or poly-crystalline wafers by mounting them and machining trenches into the wafers. The methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw (502, 504, 506, 508), laser system (900), ultrasonic machine (100), and a hot forge press (1052, 1054). The wafers are placed in an etchant solution (1402) which isotropically etches the wafers in a uniform manner, such that layers of crystalline or poly-crystalline material are removed uniformly, producing single or double bevel blades (20A-G). Nearly any angle can be machined into the wafer which remains after etching. The resulting radii of the blade edges is 5-500 nm, this is equivalent to a diamond edged blade manufactured at a fraction of the cost.

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： A composite utility knife blade (10) 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 (46) 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 (20, 22). The composite strip (46) is then annealed, and the annealed strip is straightened to eliminate any camber therein. The annealed composite strip (46) is then hardened such that the first metal portion (20) defines a surface hardness within the range of approximately 38 Rc to approximately 52 Rc, and the second metal portion (20) defines a surface hardness within the range of approximately 60 Rc to approximately 75 Rc.

摘要： A dressing device (10,90) for sharpening or conditioning of a blade (18) or the like includes one or more disk pairs (36-40,108), each having a pair of disks (52,54,110,112) respectively presenting a series of circumferentially spaced, projecting teeth (64) with openings (66) therebetween. The disks (52,54,110,112) are oriented in face-to-face relationship with the teeth (64) thereof in meshed, intercalated relationship to thereby create circumferential dressing openings (76,122). The dressing surfaces (74) of the teeth (64) are of arcuate, concave configuration so as to create a desirable gothic-arch edge on a blade (18) or the like.
