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-modified1 . 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 an at least one scoreline of said final scoreline pattern further comprises;
a toe terminus profile,
a heel terminus profile, 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, and
wherein said toe terminus profile is different from said heel terminus profile.
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 scoreline has Heel to Toe Terminus Slope Ratio of greater than about 6, said Heel to Toe Terminus Slope Ratio defined as;

7 . The method of claim 1 , wherein a slope of said toe terminus profile is less than a slope of said heel terminus profile.
8 . 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 an at least one scoreline of said final scoreline pattern further comprises;
a toe terminus profile,
a heel terminus profile, 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, and
wherein said toe terminus profile is different from said heel terminus profile, and
wherein at least one of said toe terminus profile or said heel terminus profile is chamfered, and wherein the other one of said toe terminus profile or said heel terminus profile is radiused.
9 . The method of claim 8 , said at least one scoreline is asymmetrical about said face centerline.
10 . The method of claim 8 , 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;

11 . The method of claim 10 , wherein said Heel to Toe Terminus Slope Ratio is greater than about 8.75.
12 . The method of claim 11 , wherein said Heel to Toe Terminus Slope Ratio is greater than about 13.
13 . The method of claim 8 , wherein said toe terminus profile has a slope of less than about 0.25.
14 . The method of claim 13 , wherein said toe terminus profile has a slope of less than about 0.20.
15 . The method of claim 14 , wherein said toe terminus profile has a slope of less than about 0.15.
16 . The method of claim 13 , wherein said heel terminus profile has a slope of greater than about 1.50.
17 . The method of claim 16 , wherein said heel terminus profile has a slope of greater than about 1.75.
18 . The method of claim 17 , wherein said heel terminus profile has a slope of greater than about 2.0Join the waitlist — get patent alerts
