Abstract: The invention provides a new type of putter for golfers to improve their putting accuracy and stability. The grip is shaped to help users lock all joints on their hands and arms in place, and thus limits golfers movement of those muscles. By locking all joints and muscles, golfers can concentrate on using only the back and shoulder muscles to putt, making it much easier to have the putter face perpendicular to the intended golf ball path on the x-y plane. Not only would this allow more accurate, stable putts, with repeated usage of this device, golfers will become accustomed to using their back and shoulder muscles to putt, and hence improve their putting skill even with a regular putter.

Abstract: A golf putter includes a pair of aiming arms at each end of the putter head having opposite and inward facing arcuate surfaces corresponding to the outline of a golf hole.

Abstract: A method of manufacturing a golf club head having a face insert that is mechanically isolated from the body of the club head involves inserting a face insert into a cavity formed in the body. The face insert is suspended above a bottom wall of the cavity by tabs that rest on the front face of the body. A curable liquid material, such as polyurethane, is injected between the face insert and the cavity. Once the polyurethane is cured, the tabs are machined off leaving a striking surface on the face insert that is flush with the front face of the body. Since the only part of the face insert that was in contact with the body is removed during the machining operation, the face insert is completely isolated from the body by the cured polyurethane.

Abstract: Existing golf putters basically have flat face surfaces that allow putting contact with only one point on the golf ball on any given stroke. This design provides the absolute minimum ball directional control possible for any given putt. The Victory Golf Putter indents the face of the golf club, by an area larger than the golf ball itself and with at least one (and potentially more) indention angel reversals. This design allows for a minimum of two striking points on any golf ball putted with improved, both immediate and long term, putting results thru better ball directional control, improved stroke feel, and immediate stroke education feedback for the golfer. The putter channel can be either shallow or deep allowing for personal golfer preferences to be met and a top side strike point(s) can even be added for better rolling ball ground contact.
