Abstract: A putter head including a fore body and an aft body. The fore body includes a planar front strike face, heel and toe side walls, a rear wall, a top surface and a generally planar sole. The top surface includes a sight line. The sight line extends along a first plane that is perpendicular to the strike face and to the sole, and is substantially evenly spaced from the heel and toe side walls. The aft body is coupled to the fore body and includes a rear main portion and an overhang. The rear main portion is engaged to the rear wall of the fore body, and has a central region positioned between first and second end regions. The overhang forwardly extends from the central region. The overhang includes an elongate slot extending along the first plane, and is positioned over at least a portion of the sight line.

Abstract: The front and back striking surfaces are identical mirror images of each other. If the front surface for (right handed putter) is ?2 degrees negative loft the back surface is ?2 degrees negative loft. If the front surface for a left handed putter has a ?4 degrees negative loft the back surface of the putter has ?4 degrees negative loft. Looking at the heel from the back lengthwise you would see a “V” shaped head. The center of gravity is above the center of height of the putter resulting in forward force striking above the equator or center of the golf bal due to the negative loft of the putter face resulting in immediate roll of the golf ball. The center of gravity can be raised by drilling holes lengthwise along the putter head and leaving the holes empty or adding weight.

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 has a 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 of right-handed golfers to let the club head drift or angle when attempting left-to-right breaking putts.
