A golf putter includes a compound convex surface on the face of the club head. The convex surface formed by an arc in the horizontal plane, reduces the directional inaccuracy of a slightly misaimed putt. The vertically convex curvature assists in providing overspin on the ball when it is struck, thus promoting directional accuracy for the ball as it rolls. Additional advantages are provided in a convex curved bottom surface and angled relief for the club head, which serve to reduce the drag and "digging in" of the heel, toe, or other portion of the club head on the putting surface. The shaft joins the rear of the club head at a point aligned with the center of gravity of the club head, thus reducing the tendency for the club head to be deflected when the ball is struck squarely. The upper portion of the shaft is forwardly offset, to lie in the plane of the ball when the club head is in contact with the ball; this assists the alignment of the club head with the ball. Finally, the provision of an additional bend in the club shaft provides a clearer view of the ball when addressing and putting the ball, by displacing much of the club shaft from a position between the golfer's line of sight and the ball.
