    摘要： A kitchen knife includes a spine-side member located on a spine side; and a blade-side member located on a blade side and composed of a stacked member including a stack of two or more different metallic materials. The blade-side member is thinner than the spine-side member, and a pattern is formed on the blade-side member by processing the blade-side member into a curved shape at least at a part thereof as viewed from a cutting edge side, then joining the blade-side member to the spine-side member, and performing at least one of grinding and polishing after the joining.

    摘要： A cutting insert includes a substrate and a cutting-edge insert. The substrate has, in a thickness direction of the substrate, a bottom surface, and a top surface opposite to the bottom surface. The top surface has a polygonal shape composed of a plurality of sides in a plan view as seen along the thickness direction. The top surface is provided with a projection projecting to a side opposite to the bottom surface along the thickness direction. The projection has a through-hole passing through the substrate along the thickness direction. The projection has a side surface contiguous to the top surface. The side surface is composed of a curved line protruding to a side opposite to the through-hole in the plan view as seen along the thickness direction.

    摘要： A single-crystal diamond having a first facet plane is prepared. The single-crystal diamond is fixed to the support based on the first facet plane. An X-ray image of the single-crystal diamond is captured, the X-ray image being an X-ray image in which a crystal orientation of the single-crystal diamond is associated with an X-ray emission direction by associating the support to which the single-crystal diamond is fixed with the X-ray emission direction. A position of an inclusion of the single-crystal diamond in the single-crystal diamond is specified based on the X-ray image. It is determined whether or not a shape of the diamond tool intermediate is extractable from the single-crystal diamond with the inclusion being not included in an inclusion-excluded region. The shape of the diamond tool intermediate is extracted from the single-crystal diamond with the inclusion being not included in the inclusion-excluded region.

    摘要： A tool bit for use with a power tool having a chuck and an anvil includes a first end, a second end opposite the first end, a body defining the first end of the tool bit, and a shank coupled to the body and defining the second end of the tool bit. The shank includes a slot formed through the second end. The slot is configured to receive a portion of the chuck to transfer rotational movement from the power tool to the tool bit. The shank also includes a ball detent spaced circumferentially from the slot. The ball detent is configured to receive a locking sphere of the chuck to lock the tool bit with the chuck. The slot is sized to limit insertion of the shank into the chuck, thereby providing a space between the second end of the tool bit and the anvil.
