Abstract: An improved hand tool is disclosed having an elongated handle member (40) coupled to a tool head (20) and includes a junction (60) between the handle member and a surface of the tool head that defines an elongated interface. A weld (36) is provided along substantially all of the elongated interface so that the tool head is rigidly attached to a lower end of the handle member. A gripping member (80) is coupled to an upper end of the handle member and has a top portion (88) with an arcuate profile coupled to a bottom portion (90) having a substantially U-shaped profile. The tool head includes a blade member formed of a material having a first thickness and integrally formed with a step member having a second thickness greater than the first thickness.

Abstract: A ceramic shell mold and method of making the same. The ceramic shell mold includes a facecoat layer comprised of a first ceramic material. A plurality of alternating layers are formed overlaying the facecoat layer. The alternating layers are comprised of a second ceramic material and a third ceramic material, the third ceramic material having thermophysical properties different than the second ceramic material. The second ceramic material and the third ceramic material are preferably a zircon-based material and an alumina-based material, respectively. The resultant ceramic shell mold has a greater high temperature creep resistance than a shell mold formed solely from the second ceramic material or solely from the third ceramic material.
