Abstract

A set of golf clubs, each of the clubs in the set having substantially the same loft angle and each of the clubs in the set has a shaft length that is different from the other clubs in the set. The loft angle is preferably between about 40 and 50 degrees.

Claims

1. A set of golf clubs, each of the clubs in the set having substantially the same loft angle and each of the clubs in the set having a shaft length that is different from the other clubs in the set, wherein each of the clubs has a center of gravity height from the ground that is different from the other clubs in the set and each of the clubs has a face length that is different from the other clubs in the set.

2. The set of golf clubs of claim 1, wherein the loft angle is greater than about 40 degrees.

3. The set of golf clubs of claim 1, wherein the loft angle is between about 40 and 50 degrees.

4. The set of golf clubs of claim 1, wherein each of the shaft lengths is different than the other shaft lengths by at least about 0.25 inches.

5. The set of golf clubs of claim 4, wherein each of the shaft lengths is different than the other shaft lengths by at least about 0.5 inches.

6. The set of golf clubs of claim 5, wherein each of the shaft lengths is different than the other shaft lengths by at least about 1 inch.

7. The set of golf clubs of claim 1, wherein the center of gravity height from the ground progressively increases for each club with an increase in shaft length.

8. The set of golf clubs of claim 7, wherein the center of gravity height from the ground progressively increases by at least about 0.005 inches between clubs.

9. The set of golf clubs of claim 1, wherein the center of gravity height from the ground progressively decreases for each club with an increase in shaft length.

10. The set of golf clubs of claim 9, wherein the center of gravity height from the ground progresively decreases by at least about 0.005 inches between clubs.

11. The set of golf clubs of claim 1, wherein the center of gravity height from the ground is between about 0.6 and about 0.9 inches.

12. The set of golf clubs of claim 1, wherein each of clubs has a par height that is different from the other clubs in the set.

13. The set of golf clubs of claim 12, wherein the par height progressively increases for each club with an increase in shaft length.

14. The set of golf clubs of claim 13, wherein the par height increases by at least about 0.01 inches with an increase in shaft length.

15. The set of golf clubs of claim 12, wherein the par height progressively decreases for each club with an increase in shaft length.

16. The set of golf clubs of claim 15, wherein the par height decreases by at least about 0.01 inches with an increase in shaft length.

17. The set of golf clubs of claim 1, wherein the face length progressively increases for each club with an increase in shaft length.

18. The set of golf clubs of claim 1, wherein the face length progressively decreases for each club with an increase in shaft length.

19. The set of golf clubs of claim 1, wherein each of clubs has an offset that is different from the other clubs in the set.

20. The set of golf clubs of claim 19, wherein the offset progressively increases for each club with an increase in shaft length.

21. The set of golf clubs of claim 20, wherein the offset increases by at least about 0.002 inches with an increase in shaft length.

22. The set of golf clubs of claim 19, wherein the offset progressively decreases for each club with an increase in shaft length.

23. The set of golf clubs of claim 22, wherein the offset decreases by at least about 0.002 inches with an increase in shaft length.

24. The set of golf clubs of claim 19, wherein the offset is no greater than about 0.2 inches.

25. The set of golf clubs of claim 19, wherein the offset is between about 0.3 and about 0.8 inches.
