Abstract: 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.
