Forged golf club head with improved scorelines

Abstract

A forged golf club head is disclosed. More specifically, the present invention discloses a forged golf club head with an improved scoreline profile that not only has improved precision, but also has an improved geometry to help enhance the performance of the golf club head.

What is claimed is: 
     
         1 . A method of forging a golf club head comprising:
 providing a raw forging blank,   hot pre-forging said raw forging blank to create a golf club head without scorelines,   cold pre-forging said golf club head to create a rough scoreline pattern,   polishing a face of said golf club head to remove an excess material after said cold pre-forging step, and   final forging said golf club head to create a final scoreline pattern,   wherein at least one scoreline of said final scoreline pattern further comprises:
 a toe terminus profile, 
 a heel terminus profile, 
 a face centerline defined through a center point between the toe most portion of said at least one scoreline and a heel most point of said at least one scoreline, and 
 a longitudinal axis which is perpendicular to said face centerline and spans along a length of said at least one scoreline, 
 wherein said at least one scoreline is asymmetric about said longitudinal axis. 
   
     
     
         2 . The method of  claim 1 , further comprising a step of flattening said face of said golf club head before said step of final forging said golf club head. 
     
     
         3 . The method of  claim 2 , wherein said step of flattening said face occurs after said step of hot pre-forging. 
     
     
         4 . The method of  claim 2 , wherein said step of flattening said face occurs after said step of cold pre-forging. 
     
     
         5 . The method of  claim 2 , wherein said step of flattening said face occurs after said step of polishing said face. 
     
     
         6 . The method of  claim 1 , wherein said at least one scoreline is symmetric about said face centerline. 
     
     
         7 . The method of  claim 1 , wherein said at least one scoreline is asymmetric about said longitudinal axis at said toe terminus profile and said heel terminus profile. 
     
     
         8 . The method of  claim 1 , wherein said at least one scoreline has a first length on a topline most side parallel to said longitudinal axis,
 wherein said at least one scoreline has a second length on a sole most side parallel to said longitudinal axis, and   wherein said first length is greater than said second length.
