Abstract: A head for a golf club, such as a putter, having a bottom surface, a heel end, a toe end and a striking face. The striking face extends between the heel end and the toe end, adjacent the bottom surface and extending substantially upward therefrom. The striking face has a substantially planar primary portion and a secondary portion each extending from one of the two ends and meeting at an intermediate point. Each point along the striking face has a normal direction extending normally outwardly from the striking face relative to a plane tangential to the striking face at that point. The normal direction to each point on the secondary portion is directed away from the toe end. Striking a ball off of the secondary portion imparts an additional angle to the trajectory of the ball to compensate for the tendency to let the club head drift or angle when attempting left-to-right breaking putts. Striking the ball off of the primary portion does not impart any additional angle to the trajectory of the ball.
