Abstract

A method of manufacturing an iron type golf club head, including forming an iron type golf club head blank, the iron type golf club head blank having an oversized hosel portion and an oversized body portion, the iron type golf club head blank configured to accommodate a plurality of iron type golf club heads, each iron type golf club head having a unique loft angle; and removing material from said oversized body portion of said iron type golf club head blank.

First claim

We claim:

1 . A method of manufacturing an iron type golf club head, comprising:
forming an iron type golf club head blank; said iron type golf club head blank comprising oversized hosel portion and an oversized body portion, said iron type golf club head blank configured to accommodate a plurality of iron type golf club heads, each iron type golf club head having a unique loft angle; removing material from said oversized body portion of said iron type golf club head blank.

2 . The method of claim 1 , further comprising specifying said loft angle and selectively removing material from said oversized body portion to attain said loft angle.

3 . The method of claim 1 , wherein each iron type golf club head of said plurality of iron type golf club heads has a unique lie angle.

4 . The method of claim 3 , further comprising specifying said lie angle and selectively removing material from said oversized hosel portion to attain said lie angle.

5 . The method of claim 2 , wherein said plurality of iron type golf club heads comprises a first golf club head having a first loft angle and a second iron type golf club head having a second loft angle, wherein said first loft angle is approximately 17 degrees and said second loft angle is approximately 60 degrees.

6 . The method of claim 4 , wherein said plurality of iron type golf club heads comprises a first golf club head having a first lie angle and a second iron type golf club head having a second lie angle, wherein said first lie angle is approximately 58 degrees and said second lie angle is approximately 66 degrees.

7 . The method of claim 4 , wherein said oversized hosel portion comprises an oversized shaft axis, a lie width, and a loft width, said lie width measured in a substantially heel toe direction, said loft width measured perpendicular to said lie width, said lie width and said loft width measured perpendicularly to said oversized shaft axis, wherein said lie width is greater than 20 mm.

8 . A method of manufacturing an iron type golf club head, comprising:
forming an iron type golf club head blank; said iron type golf club head blank having an oversized hosel portion, said iron type golf club head blank configured to accommodate a plurality of iron type golf club heads, each iron type golf club head having a unique lie angle; removing material from said oversized hosel portion of said iron type golf club head blank.

9 . The method of claim 8 , further comprising specifying said lie angle and selectively removing material from said oversized hosel portion to attain said lie angle.

10 . The method of claim 9 , wherein said plurality of iron type golf club heads comprises a first golf club head having a first lie angle and a second iron type golf club head having a second lie angle, wherein said first lie angle is approximately 58 degrees and said second lie angle is approximately 66 degrees.

11 . The method of claim 9 , wherein said oversized hosel portion comprises an oversized shaft axis, a lie width, and a loft width, said lie width measured in a substantially heel toe direction, said loft width measured perpendicular to said lie width, said lie width and said loft width measured perpendicularly to said oversized shaft axis, wherein said lie width is greater than 20 mm.

12 . A method of manufacturing an iron type golf club head, comprising:
forming an iron type golf club head blank; said iron type golf club head blank having an oversized hosel portion, said oversized golf club head blank configured to accommodate a plurality of iron type golf club heads, each iron type golf club head having a unique loft angle; removing material from said oversized hosel portion of said iron type golf club head blank.

13 . The method of claim 12 , further comprising specifying said loft angle and selectively removing material from said oversized hosel portion to attain said loft angle.

14 . The method of claim 12 , wherein each iron type golf club head of said plurality of iron type golf club heads has a unique lie angle.

15 . The method of claim 14 , further comprising specifying said lie angle and selectively removing material from said oversized hosel portion to attain said lie angle.

16 . The method of claim 13 , wherein said plurality of iron type golf club heads comprises a first golf club head having a first loft angle and a second iron type golf club head having a second loft angle, wherein said first loft angle is approximately 17 degrees and said second loft angle is approximately 60 degrees.

17 . The method of claim 15 , wherein said plurality of iron type golf club heads comprises a first golf club head having a first lie angle and a second iron type golf club head having a second lie angle, wherein said first lie angle is approximately 58 degrees and said second lie angle is approximately 66 degrees.

18 . The method of claim 13 , wherein said oversized hosel portion comprises an oversized shaft axis, a lie width, and a loft width, said oversized shaft axis comprising the average of lie angle and loft angle of said plurality of iron type golf club heads, said lie width measured in a substantially heel toe direction, said loft width measured perpendicular to said lie width, said lie width and said loft width measured perpendicularly to said oversized shaft axis, wherein said loft width is greater than 20 mm.

19 . The method of claim 15 , wherein said oversized hosel portion comprises an oversized shaft axis, a lie width, and a loft width, said lie width measured in a substantially heel toe direction, said loft width measured perpendicular to said lie width, said lie width and said loft width measured perpendicularly to said oversized shaft axis, wherein said lie width is greater than 20 mm.

20 . The method of claim 13 , wherein forming said iron type golf club head blank comprises forging said iron type golf club head blank and wherein removing material from said oversized hosel portion comprises machining said iron type golf club head blank.
