摘要： A cutting tool, such as a kitchen knife, has a handle with an outer grip surface. A blade extends from a distal end of the handle along a central axis. The blade is formed of a metal material and has opposing first and second side surfaces that converge to a cutting edge having a plurality of continuous segments separated by a series of spaced-apart channels. Each channel is formed by an interior sidewall that extends into a body portion of the blade from the first side surface to the second side surface. Each of the channels has a channel width extending in a direction along the cutting edge, and a channel depth orthogonal to the channel width. The channels are formed using a cold forging operation on the first side surface to provide localized work hardened portions of the metal material adjacent the respective channels.

摘要： A process for partially silver electroplating the metal surface of a flat silver part wherein part of the surface is covered prior to silvering with a plating-resistant dipping enamel. A separation surface is provided between the exposed surface of the part to be covered with the dipping enamel and the exposed surface of the lengthwise adjacent part to be silvered. The separation surface consists of a material which is more difficult to wet with the dipping enamel than the metal of the surface to be covered. Preferably, the separation surface is the peripheral surface of a spacer lamination composed of polytetrafluoroethylene.

摘要： A clamp-type blade holder including blade edge angle determining bars for guiding the sharpening of a blade edge on a flat sharpening surface, such as a hone. The blade holder includes guide bars coacting with the blade edge to engage the hone and maintain the sharpening angle the same during all stroking on the hone, thereby producing an accurate sharpening angle that will enable a razor edge. The guide bars are adjustable in one embodiment to permit quick and easy change of the sharpening angle.

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.
