Abstract: A golf ball having a surface with an alignment indicia which includes a longitudinal segment and a latitudinal segment is disclosed herein. Preferably, the longitudinal segment extends along a pole of the golf ball and has a length ranging from 1.00 inch to 1.5 inches.

Abstract: The present invention is a golf club (30) having a club head main body (34) with a recess (38), an polymer insert (40) in the recess (38), an isolation layer (52) and a weight body (50). The polymer insert (40) is composed of a thermosetting polyurethane material having a Shore D hardness in the range of 42 to 55, and a Bayshore rebound in the range of 51 to 60. The preferred thermosetting polyurethane material is formed from a p-phenylene diisocyanate prepolymer and a curing agent. The golf club (30) is preferably a putter, however, it may be a wood or an iron. The particular thermosetting polyurethane provides a soft striking face for feel and a good rebound for distance. The weight body (50) is preferably composed of a tungsten alloy, and the isolation layer (52) is preferably composed of a thermoplastic polyurethane.

Abstract: A golf ball and putter alignment combination is disclosed herein. The golf ball has a surface with alignment indicia which includes a longitudinal segment and a latitudinal segment. Preferably, the longitudinal segment extends along a pole of the golf ball and has a length ranging from 1.00 inch to 1.5 inches. The putter has an alignment indicia that is aligned with the alignment indicia of the golf ball to allow for a more accurate putt.

Abstract: A golf club (20) with an internal hosel (38), a shaft (40) and a hosel liner (50) is disclosed herein. The hosel liner (50) reduces axial stress on the shaft (40) during impact of the golf club (20) with a golf ball. The hosel liner (50) is preferably composed of a polycarbonate material that has a flexural modulus in the range of 300,000 pounds per square inch to 1,000,000 pounds per square inch. Preferably, the golf club head (22) has a large volume, greater than 300 cubic centimeters, and weighs less than 215 grams. Preferably, the shaft (40) is composed of graphite and weighs between 40 grams to 80 grams.

Abstract: The present invention is a golf club (30) having a club head main body (34) with a hollow interior (49), a support layer 41 defining a depth of a recess (38), a polymer insert (40) in the recess (38), an isolation layer (52) and a weight body (50).

Abstract: A bending plate for use in adjusting a lie and/or loft of a golf club head. The bending plate comprises means for minimizing or reducing mechanical stresses within a face region and face insert plate of the golf club head, when the golf club head is placed in a clamping apparatus. Thus, the bending plate protects the face insert plate of the club head during a lie and/or loft adjustment of the club head. The bending plate also includes means for establishing proper positioning of the bending plate over the face insert plate and/or face region of the golf club head.
