  • Patent number: 7621503
    Abstract: A multipurpose hand tool includes a head, a shank and a handle. The head includes a nail-pulling section, a bridge section and a nail-striking section. The shank extends from the bridge section to the handle. Preferably, the nail-pulling section defines a nail-head-receiving cavity accessible from the rear with nail-body-receiving upper and lower slots leading thereto. In the preferred embodiment, the nail pulling section comprises a segmented top wall, a segmented bottom wall and side walls that define the cavity. The nail pulling section and nail striking section preferably include base surfaces that are substantially flat and aligned in a common plane. The sides of the shank extend downward from the bridge section at a direction substantially orthogonal to this common plane to realize a T-square that can be used for orthogonal line marking. The shank preferably includes other features that are used for measurement and marking.
