According to an aspect of the present invention the putter heads is of rectangular shape having two striking sides, each having different performance characteristics. One side may have a plain face insert which may provide more feel for the player on impact with the golf ball. This may help the player to strike the golf ball with more feel and control. The other side of the rectangular shaped putter head may have grooves in the face insert which may promote more roll of the golf ball on impact. This may help the player to strike the golf ball promoting more ball roll and may help the ball roll rather than slide on impact.

According to an aspect of the present invention, the putter may be rotated 180% to enable using any of the two striking faces of the putter. The rotation of the putter may be done by tightening/untightening a screw located on the hosel connecting the putter body to the putter head. This screw when untightened will allow the putter head to rotate 180% and choose the striking face required. Once tightened the putter head position becomes fixed on the chosen striking side and does not permit any rotation thereof.

According to an aspect of the present invention the screw is operated by a golf tool having an oval shape on the holding end and a hexagonal shape on the operating end of the golf tool. The golf tool may be used to tighten/untighten the screw located on the hosel between the putter head and putter body. The screw in complete untightened position allows the putter head to rotate 180% to select any one of the two striking faces of the putter head. When the screw is tightened, the putter head becomes fixed making only side the playable striking side of the putter.

According to an aspect of the present invention the putter head may have two striking faces. Each striking face may have an insert on the impact area of the head. Each insert of the two striking face of the putter head may be of a different material, one being harder and the other softer in composition in order to have two different kind of characteristics on impact with the golf ball. The insert may be contained within the striking face of the putter head.

According to another aspect of the present invention the golf tool used to operate the screw may be of a general design like an Allen key to loosen or tighten the screw on the hosel. Once tightened, the striking face will be fixed as the operating striking side of the putter head.
