    摘要： 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.
