Abstract
Abstract A golf club used in putting a golf ball having an elongated head constructed of relatively lightweight, preferably aluminum, material at its central portion and having relatively heavier metal end portions. In proportion to the diameter of a standard U.S.G.A. golf ball, the central aluminum head portion is approximately 11/2 to 3 times as long; the end portions are approximately 1/2 to 11/2 times as long. The weight distribution between the head central portion in relation to the heavier metal end portions is such that 60% to 90% of the total weight of the elongated head is contained in the end portions. This weight distribution increases the rotational inertial stability of the club head, improving a golfer's putting accuracy. The central portion of the head is connected to a conventional golf club shaft for use.
