Abstract

A golf club and/or shaft with improved weighting characteristic is disclosed. More specifically, the present invention discloses to a golf club and/or shaft wherein the improved weighting distribution stems from an increase in the mass of the golf club and/or shaft at a specific distance away from the butt end or proximal end of the golf club to help increase the feel and minimize the dispersion of the golf shot by fine tuning the pull and or draw tendencies of a golf shot.

Claims

1. A shaft for a golf club comprising:

a butt end having a first shaft diameter,

a tip end having a second shaft diameter, wherein said first shaft diameter is greater than said second shaft diameter, and

a heavy weighted section, located at a distance of between exactly 10 and exactly 15 inches away from said butt end of said shaft, and

wherein said heavy weighted section further comprises a dense layer, having a material density greater than a material density of said shaft, said dense layer is longitudinally located between an internal wall of said shaft and an external wall of said shaft from a beginning of said heavy weighted section to an end of said heavy weighted section.

2. The shaft of claim 1, wherein said shaft further comprises a second lightweight section, located at a distance of between exactly 5 and exactly 10 inches away from said butt end of said shaft,

wherein said mass of said heavy weighted section is greater than about 140% of a mass of said second lightweight section.

3. The shaft of claim 2, wherein said mass of said heavy weighted section is greater than about 145% of said mass of said second lightweight section.

4. The shaft of claim 3, wherein said mass of said heavy weighted section is greater than about 150% of said mass of said second lightweight section.

5. The shaft of claim 2, wherein said heavy weighted section has a mass of greater than about 9 grams.

6. The shaft of claim 2, wherein said heavy weighted section has a mass of greater than about 9.5 grams.

7. The shaft of claim 2, wherein said heavy weighted section has a mass of greater than about 10 grams.

8. The shaft of claim 6, wherein said dense layer is created using a powder.

9. The shaft of claim 6, wherein said dense layer is created using a layer of tungsten metal.

10. The shaft of claim 6, wherein said dense layer is created using a layer of steel.

11. A shaft for a golf club comprising:

a butt end having a first shaft diameter,

a tip end having a second shaft diameter, wherein said first shaft diameter is greater than said second shaft diameter, and

a heavy weighted section, located at a distance of between exactly 10 and exactly 15 inches away from said butt end of said shaft, and

wherein said heavy weighted section has a mass of greater than about 9 grams,

wherein said heavy weighted section further comprises a dense layer, said dense layer is centrally located between an internal wall of said shaft and an external wall of said shaft, and wherein said dense layer is created using a dense powder.

12. The shaft of claim 11, wherein said heavy weighted section has a mass of greater than about 9.5 grams.

13. The shaft of claim 12, wherein said heavy weighted section has a mass of greater than about 10 grams.
