A golf putter having a uniquely configured striking surface is claimed. The putter has a striking surface that is twisted between the toe of the putter and the heel of the putter. The loft angle associated with the striking surface of the putter varies from a positive loft angle near the heel to a negative loft angle near the toe. The striking surface of the putter has a midline. The striking surface is twisted about the mid-line. The plane of the twisted striking surface is also slightly curved to eliminate any concave curvatures created by the twist. A non-metallic insert is added to the striking surface. The non-metallic insert has thickness that varies as a function of its position along the mid-line.
