  • Patent number: 4958540
    Abstract: An impact tool (A) is disclosed which includes an arrangement of angularly disposed shanks which provide a mechanical advantage to the impact force. A first shank (10) provides a grip (12) held generally orthogonal by hand (14) of the user. A second shank (16) extends generally in a straight line to the arm (24) when the grip is held in the hand, and a third shank (18) extends from the second shank (16) at an angle and terminating in an impact head (20). The device thrusts generally forward with the arm and shoulder during impact with little or no wrist movement as encountered in the sense of a conventional handle. Control is afforded by the angle arrangement of the handle as well as increased force.
