An improved golf putter club is disclosed in which the club head, hosel, shaft and grip are so configured that the club\s total weight is perfectly centered and balanced about the club\s shaft axis, resulting in multi-directional stability, i.e., infinite balancing, against any static forces causing the putter club head to rotate off line about the shaft, grip, and hosel axis. Such rotational stability eliminates any inherent twisting forces of the putter head during use. An extremely high moment of inertia about the club head\s center of gravity results from use of a relatively heavyweight material for the ball striking face, the club heel and toe ends, and the adjacent sole portions, while an insert formed of a relatively lightweight material is used to fill in the club head\s central area where heavyweight material is absent. This high rotational moment of inertia assures that when a golf ball is hit off-center (i.e., struck on the face at a distance from the club head\s center of gravity) only a minimal angular acceleration is produced by the club head on the golf ball being struck. The above advantages are provided in a putter having a slight onset design.

An improved golf club for preventing unwanted angular acceleration and having a high moment of inertia to resist twisting on off-center hit shots, said improved golf club having a shaft carrying a grip, a club center of gravity, a club head affixed to said shaft, said club head having a front striking face, a sole surface, an upper surface, a heel, a toe, a hosel for affixing said shaft to said club head, and a club head center of gravity, the improvement comprising: a major club head component formed of a heavyweight material and forming said striking face and said hosel, said major club head component having a massive weighted toe portion, a massive weighted heel portion, and an elongated central void area formed both behind said striking face between said massive weighted toe and heel portions and along part of said upper surface and part of said sole surface; an insert component formed of a lightweight material and operable, when securely affixed to said major club head component, to structurally and aesthetically completely fill said central void area while permitting the differential in weight between said heavyweight material and said lightweight material, for a given weight golf club head, to be distributed in said massive weighted toe and heel portions, to thereby provide uniform weight distribution and to create a high moment of inertia for said golf club, both about said club head center of gravity and said club center of gravity; a strike point located centrally of said striking face along the length thereof, said club head center of gravity being in direct alignment with said strike point in a plane perpendicular to the striking face; and said hosel being so positioned and aligned relative to said club head as to assure that the central axis of said shaft is coaxially aligned with both said club head center of gravity and said club center of gravity, thereby resulting in an infinitely balanced golf club which prevents unwanted angular acceleration from being imparted to said golf club head by a golf ball on center hit impacts.
