Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A golf club comprising:
 a club head;   a shaft coupled to the club head, comprising:
 a shaft bend disposed along a unitary portion of the shaft at a specially configured shaft bend height above the club head with the shaft bend dividing the shaft into a shaft lower portion and shaft upper portion, the specially configured shaft bend height configured for a strong arc swing style; 
 wherein a shaft axis extends through a longitudinal centerline of the shaft upper portion and a horizontal plane of the club head extends through a strike face centerpoint of the club head with the shaft axis intersecting the horizontal plane at an intersection distance away from the strike face centerpoint such that a center of gravity of the golf club is moved away from the strike face centerpoint by nature of the intersection distance, the intersection distance defined by the specially configured shaft bend height and specially configured for the strong arc swing style; and 
 wherein the shaft bend disposed along the unitary portion of the shaft is configured to impart a toe-down hang angle to the golf club, the toe-down hang angle specially configured for the strong arc swing style. 
   
     
     
         2 . The golf club of  claim 1 , wherein:
 the specially configured shaft bend height comprises a low bend height such that the shaft bend is disposed along the unitary portion of the shaft at less than 85 mm above a horizontal plane of the club head, the low bend height specifically configured for the strong arc swing style.   
     
     
         3 . The golf club of  claim 1 , wherein:
 the shaft bend comprises a shaft bend angle comprising a range of 146 degrees to 174 degrees.   
     
     
         4 . The golf club of  claim 1 , wherein:
 the toe-down hang angle is greater than or equal to 48 degrees.   
     
     
         5 . The golf club of  claim 1 , wherein:
 the strong arc swing style is associated with a swing rotation of an individual swinging the golf club comprising a strong arc swing rotation of 7.5 or more degrees.   
     
     
         6 . The golf club of  claim 1 , wherein:
 a ratio of the intersection distance to a length of the club head comprises greater than 0.155.   
     
     
         7 . The golf club of  claim 1 , wherein:
 the shaft bend creates an offset distance between the shaft axis and the strike face centerpoint of the club head.   
     
     
         8 . A golf club comprising:
 a club head;   a shaft coupled to the club head, comprising:
 a shaft bend disposed along a unitary portion of the shaft at a specially configured shaft bend height above the club head with the shaft bend dividing the shaft into a shaft lower portion and shaft upper portion, the specially configured shaft bend height configured for a slight arc swing style; 
 wherein a shaft axis extends through a longitudinal centerline of the shaft upper portion and a horizontal plane of the club head extends through a strike face centerpoint of the club head with the shaft axis intersecting the horizontal plane at an intersection distance away from the strike face centerpoint such that a center of gravity of the golf club is moved away from the strike face centerpoint by nature of the intersection distance, the intersection distance defined by the specially configured shaft bend height and specially configured for the slight arc swing style; and 
 wherein the shaft bend disposed along the unitary portion of the shaft is configured to impart a mid-hang hang angle to the golf club, the mid-hang hang angle specially configured for the slight arc swing style. 
   
     
     
         9 . The golf club of  claim 8 , wherein:
 the specially configured shaft bend height comprises a medium bend height such that the shaft bend is disposed along the unitary portion of the shaft at 70 mm to 85 mm above a horizontal plane of the club head, the medium bend height specifically configured for the slight arc swing style.   
     
     
         10 . The golf club of  claim 8 , wherein:
 the shaft bend comprises a shaft bend angle comprising a range of 146 degrees to 174 degrees.   
     
     
         11 . The golf club of  claim 8 , wherein:
 the mid-hang hang angle comprises 16 to 48 degrees.   
     
     
         12 . The golf club of  claim 8 , wherein:
 the slight arc swing style is associated with a swing rotation of an individual swinging the golf club comprising a slight arc swing rotation of approximately 3.5 degrees to 7.5 degrees.   
     
     
         13 . The golf club of  claim 8 , wherein:
 a ratio of the intersection distance to a length of the club head comprises 0.05 to 0.155.   
     
     
         14 . The golf club of  claim 8 , wherein:
 the shaft bend creates an offset distance between the shaft axis and the strike face centerpoint of the club head.   
     
     
         15 . A golf club comprising:
 a club head;   a shaft coupled to the club head, comprising:
 a shaft bend disposed along a unitary portion of the shaft at a specially configured shaft bend height above the club head with the shaft bend dividing the shaft into a shaft lower portion and shaft upper portion, the specially configured shaft bend height configured for a straight stroke swing style; 
 wherein a shaft axis extends through a longitudinal centerline of the shaft upper portion and a horizontal plane of the club head extends through a strike face centerpoint of the club head with the shaft axis intersecting the horizontal plane at an intersection distance away from the strike face centerpoint such that a center of gravity of the golf club is moved away from the strike face centerpoint by nature of the intersection distance, the intersection distance defined by the specially configured shaft bend height and specially configured for the straight stroke swing style; and 
 wherein the shaft bend disposed along the unitary portion of the shaft is configured to impart a face-balanced hang angle to the golf club, the face-balanced hang angle specially configured for the straight stroke swing style. 
   
     
     
         16 . The golf club of  claim 15 , wherein:
 the specially configured shaft bend height comprises a high bend height such that the shaft bend is disposed along the unitary portion of the shaft at greater than 95 mm above a horizontal plane of the club head, the high bend height specifically configured for the straight stroke swing style.   
     
     
         17 . The golf club of  claim 15 , wherein:
 the face-balanced hang angle comprises less than 16 degrees.   
     
     
         18 . The golf club of  claim 15 , wherein:
 the straight stroke swing style is associated with a swing rotation of an individual swinging the golf club comprising a straight stroke swing rotation of approximately 0 degrees to 3.5 degrees.   
     
     
         19 . The golf club of  claim 15 , wherein:
 a ratio of the intersection distance to a length of the club head comprises less than 0.05.
