  • Patent number: 5759115
    Abstract: An improved golf club head, specifically for a putter, which has a conventional putting face on the front and two cantilevered fins connected on the back of the putter head. The fins are oriented perpendicularly to the putting face, extending to the back of the putter, so that one is connected adjacent the top of the putter head and the other adjacent the bottom of the putter head. The fins are partially connected to the putter along the tapered part of the fin, allowing the large part of the fin not to be directly attached to the putter's back face. The upper fin is connected to one end of the putter's back face and the lower fin is connected to the other end of the putter's back face, thereby locating the center of mass of the fin arrangement along the vertical center line of the putter's back face.
