摘要： Method for enhancing sharpness of a cutting tool. A blade portion is cold forged by applying a force to a first side of the blade portion using a form tool projection to form a notch such that a portion of the metal material from the first side of the blade is work hardened and plastically deformed to extend through a plane along which the second side extends. A secondary grinding operation is applied to the second side of the blade portion to remove the portion of the metal material that extends beyond the plane along which the second side extends and sharpen a cutting edge extending between the first and second sides. The form tool projection is a radially extending projection of a rotatable knurl roller which rotates to form a sequence of spaced apart cold forged notches along the cutting edge.

摘要： Apparatus for cutting media. In some embodiments, a cutting tool has a blade with opposing first and second side surfaces that converge to a cutting edge which continuously extends along a length of the blade. Spaced apart, microscopically sized first and second channels formed in the cutting edge extend from the first side surface to the second side surface and are separated by a segment of the cutting edge having a first length along the length of the blade. Each of the first and second channels have a channel width extending along the length of the blade and a channel depth orthogonal to the channel width. In some embodiments, the channel width is less than the first length and has a notch depth of from about 0.0003 inches to about 0.005 inches.

摘要： A composite utility knife blade and method of making such a blade involves butt joining a tool steel wire to a front edge of an alloy steel backing strip. The wire is electron beam welded to the backing strip to form a composite strip defining a first metal portion formed by the alloy steel backing strip, a second metal portion formed by the tool steel wire, and a weld region 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 57 Rc.

摘要： A process for making a cutting instrument includes cutting a blank from a plate or strip of Type 60 Nitinol, having a thickness of between 0.005″-0.500″ using an abrasive waterjet, wire electron discharge machining or laser cutting, and grinding top and bottom surfaces of the blank by rotating a grinder having cubic boron nitride or diamond abrasive particles on a cutting surface of said grinder against the knife blank at a surface speed of about 5000 to 7000 surface feet per minute and grinding to a depth of about 0.001 to 0.005 inches per pass to remove material along the blade surface. The surface of the blade is polished to a surface finish smoother than 20 microinches RMS using Turkish emery abrasive grinding/polishing materials on a buffing wheel driven by a high power motor. The blade is then finish polished to a mirror-like luster of 2 microinches RMS or less using a fine diamond buffing compound and a buffing wheel running at about 3000 RPM. An edge is ground into the polished blade blank using an Arkansas stone grinder.

摘要： This application relates to a method of manufacturing a knife using a multilayer material. In one aspect, the method includes preparing a multilayer material for manufacturing a knife, and heating and then forging the multilayer material to form a knife-shaped structure including a blade part and a handle part. The method also includes grinding the blade part to form a sharpened knife-edge and applying mud, including kaolin and white clay, to an entire surface of the knife-shaped structure and removing the mud applied to the blade part. The method further includes heating the knife-shaped structure applied with the mud, and quenching the heated knife-shaped structure through oil-cooling. The method further includes etching a surface of the quenched knife-shaped structure to form a pattern on the surface and grinding the surface-etched knife-shaped structure to form a knife having a final shape.

摘要： The present invention relates to a cutting blade such as a kitchen knife blade. The cutting blade comprises a cutting edge, a spine and opposite side surfaces. A tapered portion of the blade extends longitudinally and adjacent to the cutting edge in which a thickness of the blade defined as a transverse distance between the opposite side surfaces tapers towards the cutting edge. The cutting blade includes one or more broad recesses provided in one or more side surfaces of the blade, wherein at least one of the broad recesses is bounded at vertically opposite sides by the tapered portion and the spine and at longitudinally opposite sides by narrow supporting elements extending from the spine to the tapered portion. Embodiments of the cutting blade have a substantially reduced average wedge thickness which reduces cutting resistance to due to the wedging effect. Embodiments of the cutting blade provide a reduced total surface area of the one or more sides surfaces in contact with an item being cut by the blade which reduces cutting resistance due to friction between the side surfaces of the blade and the item. The present invention also provides for methods of forming a cutting blade, such as by near-net or additive manufacturing techniques.

摘要： A method of manufacturing a part having a beveled edge with a serration formed in the beveled edge. The method includes positioning a part between a first die piece and a second die piece; and moving the first die piece relative to the second die piece. The movement results in both shearing a portion of the part to create the beveled edge, and serrating the beveled edge to create the serration.
