  • Publication number: 20080066582
    Abstract: A hammer structure with a hammerhead having an impact face with a shape of the letter “D” is disclosed. The impact face has three straight sides, and one arc-shaped side; as a result, the surface area of the impact face is substantially larger than that of a conventional O-shaped impact face with the same width and height. Since the effective impact face is enlarged, the point of force application can be more precisely controlled, regardless of whether the hammering is carried out on a single wall, a corner between two walls, or any similar locations. Moreover, the problems caused by dead spots can be overcome.
