Abstract: Embodiments of the disclosure relate to a reciprocating saw blade. The reciprocating saw blade includes a body having a first end, a second end spatially disposed from the first end, a spine edge, and a cutting edge opposite to the spine edge. The reciprocating saw blade also includes a plurality of teeth defining a cutting portion of the cutting edge. Each tooth of the plurality of teeth includes a base having a unitary construction with the body. The base is made of a first material having a first hardness. A tip is welded to the base, and the tip is made of a cemented ceramic material having a second hardness that is greater than the first hardness. The cemented ceramic material includes tungsten carbide particles and at least 3 wt % of other particles including one or more cubic carbides.

Abstract: An anvil for an impact tool including an impact receiving portion at an end of the anvil, the impact receiving portion including a lug having an impact receiving surface that receives impact from a hammer of the rotary power tool, a shank portion extending from the impact receiving portion, a drive portion located at an end of the shank portion opposite from the impact receiving portion, the drive portion including a plurality of drive surfaces configured to engage a tool bit, and a hardened layer formed on at least one of the drive portion or the impact receiving surface, the hardened layer having a higher hardness than a remaining portion of the anvil. The hardened layer is formed by a heating process.
