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.

Claims

exact text as granted — not AI-modified
1 . A forged golf club head comprising:
 a striking face portion located at a frontal portion of said forged golf club head, and   a hosel attached to a heel portion of said forged golf club head,   wherein a frontal surface of said striking face portion further comprises a plurality of forged scorelines,
 wherein an at least one scoreline of said plurality of forged scorelines further comprises;
 a toe terminus profile from a cross-sectional view, 
 a heel terminus profile from a cross-sectional view, 
 a central constant depth portion, and 
 a face centerline, defined as 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, 
 wherein said toe terminus profile is different from said heel terminus profile, 
 wherein said plurality of forged scorelines are formed without any machining, and 
 wherein said heel terminus profile is non-vertical and chamfered. 
 
   
     
     
         2 . The forged golf club head of  claim 1 , wherein said at least one scoreline is asymmetrical about said face centerline. 
     
     
         3 - 5 . (canceled) 
     
     
         6 . The forged golf club head of  claim 1 , wherein said at least one scoreline has Heel to Toe Terminus Slope Ratio of greater than about 6, said Heel to Toe Terminus Slope Ratio defined as;
