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

exact text as granted — not AI-modified
What is claimed is:  
     
         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 has a shaft 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 that 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 that 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 that the other shaft lengths by at least about 1 inch.  
     
     
         7 . The set of golf clubs of  claim 1 , wherein each of clubs has a center of gravity height from the ground that is different from the other clubs in the set.  
     
     
         8 . The set of golf clubs of  claim 7 , wherein the center of gravity height from the ground progressively increases for each club with an increase in shaft length.  
     
     
         9 . The set of golf clubs of  claim 8 , wherein the center of gravity height from the ground progressively increases by at least about 0.005 inches between clubs.  
     
     
         10 . The set of golf clubs of  claim 7 , wherein the center of gravity height from the ground progressively decreases for each club with an increase in shaft length.  
     
     
         11 . The set of golf clubs of  claim 10 , wherein the center of gravity height from the ground progressively decreases by at least about 0.005 inches between clubs.  
     
     
         12 . The set of golf clubs of  claim 7 , wherein the center of gravity height from the ground is between about 0.6 and about 0.9 inches.  
     
     
         13 . The set of golf clubs of  claim 1 , wherein each of clubs has a center of gravity distance from the leading edge that is different from the other clubs in the set.  
     
     
         14 . The set of golf clubs of  claim 13 , wherein the center of gravity distance from the leading edge progressively increases for each club with an increase in shaft length.  
     
     
         15 . The set of golf clubs of  claim 14 , wherein the center of gravity distance from the leading edge progressively increases by at least about 0.005 inches between clubs.  
     
     
         16 . The set of golf clubs of  claim 13 , wherein the center of gravity distance from the leading edge progressively decreases for each club with an increase in shaft length.  
     
     
         17 . The set of golf clubs of  claim 16 , wherein the center of gravity distance from the leading edge progressively decreases by at least about 0.005 inches between clubs.  
     
     
         18 . The set of golf clubs of  claim 13 , wherein the center of gravity distance from the leading edge is between about 0.4 and about 0.6 inches.  
     
     
         19 . The set of golf clubs of  claim 1 , wherein each of clubs has a toe height that is different from the other clubs in the set.  
     
     
         20 . The set of golf clubs of  claim 19 , wherein the toe height progressively increases for each club with an increase in shaft length.
