Abstract
A unique golf putter clubhead, when attached to a shaft, assures better directional control of a golf ball travel when use for its primary purpose of putting a golf ball. The putter clubhead is formed along a longitudinal axis generally transverse to the plane defined by the ball-striking face. The ball-striking face may be formed in a radial surface defining either a spherical or cylindrical arc.
