A putter head fashioned from a block metal having a conventional face, but having a mass relieved portion behind the face, with greatest mass relief at the sole of the club and a lesser amount of mass relief extending upwardly to the top surface of the club which has conventional dimensions and shape. Since the greatest amount of mass relief is at the bottom of the club, the mass relief is said to be inverted. A pair of inclined ribs behind the central portion of the face add stiffness to the club. The club has a raised center of gravity intended to be in alignment with the center of a golf ball. A plug of heavy metal may be centered on the center of gravity to add stiffness at the zone. Although the club would typically be made out of aluminum or steel, a club, without the plug, could be made of an ultra heavy metal, such as depleted uranium, and be no heavier than a regular club due to the inverted mass relief.
