Patent ID: 8070621

Claim:
A golf club set comprising m or more wood type golf clubs (wherein, m is an integer of no less than 2) having a loft angle of greater than 20 degrees, wherein provided that the face progression b 2 of these m clubs is defined as from b 2 (1) to b 2 (m) following the ascending order of the loft angle a 2 of the club from the smallest value of a 2 , the set satisfies the relationships of: b 2(1)â‰§ b 2(2)â‰§ . . . â‰§ b 2( m ); and b 2(1)> b 2( m ), and wherein in all clubs having a loft angle of greater than 20 degrees, the ratio (a 2 /b 2 ) of the loft angle a 2 (degree) to the face progression b 2 (mm) is 0.7 or greater and 2.0 or less.
