Abstract: A hammer having an improved head assembly. The hammer head assembly has a head portion, a shank portion, and a claw portion. The head portion has a front face having a triangular configuration. The head portion also has a horizontally oriented top wall and two side walls that converge downwardly toward their bottom ends where they meet. The center of the front face of the head portion lies on an axis that is perpendicular to the longitudinal axis of the handle and they intersect at the center of gravity of the hammer head assembly. The top end of the shank portion is flat so that the hammer can free stand on the surface. There is a rounded indentation between the shank portion and the claw portion so that it may be rested upon a block or cats paw for extra leverage. A T-shaped slot may be formed in the top end of the handle and it may have a related magnet for detachably capturing the head of a nail therein for hammering purposes.
