Putter with bi-material shaft
A process for manufacturing a putter with a bi-material shaft is disclosed herein. The putter comprises a putter head, the bi-material shaft, a mass member and a grip. The bi-material shaft comprises a body with a tip end and a butt end. The body comprises a metal section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point. The mass member is positioned within an opening at the butt end of the shaft. Mass from the shaft is transferred to the club head and the mass member in the butt end of the shaft.

a body with a tip end and a butt end, the body comprising a steel section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point;
wherein the butt end has an outer diameter ranging from about 0.550 inch to about 0.625 inch;
wherein the composite section is from 60 to 80 percent of the length of the shaft and the composite section is less than 25 percent of the mass of the shaft.
2. The shaft according to claim 1 further comprising a mass member that has a mass ranging from 20 grams to 40 grams.
3. The shaft according to claim 2 wherein the mass member has a mass of 30 grams.
4. A putter comprising:
a club head having a mass ranging from 300 grams to 400 grams; and
a shaft comprising:
a body with a tip end and a butt end, the body comprising a steel section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point, and
wherein the butt end has an outer diameter ranging from about 0.550 inch to about 0.625 inch;
wherein the composite section is from 60 to 80 percent of the length of the shaft and the composite section is less than 25 percent of the mass of the shaft; and
a grip having a mass ranging from 40 grams to 65 grams.
5. The golf club according to claim 4 further comprising a mass member that has a mass ranging from 20 grams to 40 grams.
