Abstract

A set of iron type golf club heads comprising a plurality of iron type golf club heads, the plurality of iron type golf club heads comprising a long iron, a mid iron, and a short iron; wherein each of the plurality of iron type golf club heads comprise a striking face, and wherein each of the plurality of iron type golf club heads comprise a plurality of grooves formed in the striking face extending generally from a heel side of the striking face towards a toe side of the striking face; wherein the plurality of grooves of each of the plurality of iron type golf club heads comprise a groove pitch measurement, wherein the groove pitch of the plurality of grooves of the long iron is greater than the groove pitch of the plurality of grooves of the short iron.

Claims (33)

1. A set of iron type golf club heads, comprising:

a plurality of iron type golf club heads, said plurality of iron type golf club heads comprising a long iron having a loft angle greater than or equal to 15 degrees and less than 26 degrees, a mid iron having a loft angle greater than or equal to 26 degrees and less than 37 degrees, and a short iron having a loft angle greater than or equal to 37 degrees and less than 47 degrees;

wherein each of said plurality of iron type golf club heads comprise a striking face, and wherein each of said plurality of iron type golf club heads comprise a plurality of grooves formed in said striking face extending generally from a heel side of said striking face towards a toe side of said striking face;

wherein said plurality of grooves of each of said plurality of iron type golf club heads comprise an edge radius, wherein said edge radius of said plurality of grooves of said long iron is greater than said edge radius of said plurality of grooves of said short iron;

wherein said edge radius of said plurality of grooves is the radius of the edge at the intersection of a wall of each groove of said plurality of grooves and an outer surface of the striking face;

wherein said edge radius of said plurality of grooves of said short iron is less than 0.005″.

2. The golf club head of claim 1 , wherein said edge radius of said plurality of grooves of said mid iron is greater than said edge radius of said short iron.

3. The golf club head of claim 1 , wherein said edge radius of said plurality of grooves of said mid iron is less than said edge radius of said long iron.

4. The golf club head of claim 1 , wherein said edge radius of said plurality of grooves of said long iron is greater than or equal to 0.007″ and less than or equal to 0.020″.

5. The golf club head of claim 1 , wherein said edge radius of said plurality of grooves of said mid iron is greater than or equal to 0.005″ and less than or equal to 0.007″.

6. The golf club head of claim 1 , wherein said edge radius increases through said set of iron type golf club heads in a substantially linear relationship as said loft of each of said plurality of iron type golf club heads decreases.

7. A set of iron type golf club heads, comprising:

a plurality of iron type golf club heads, said plurality of iron type golf club heads comprising a long iron having a loft angle greater than or equal to 15 degrees and less than 26 degrees, a mid iron having a loft angle greater than or equal to 26 degrees and less than 37 degrees, and a short iron having a loft angle greater than or equal to 37 degrees and less than 47 degrees;

wherein each of said plurality of iron type golf club heads comprise a striking face, and wherein each of said plurality of iron type golf club heads comprise a plurality of grooves formed in said striking face extending generally from a heel side of said striking face towards a toe side of said striking face;

wherein said plurality of grooves of each of said plurality of iron type golf club heads comprise a draft angle, wherein said draft angle of said plurality of grooves of said long iron is less than said draft angle of said plurality of grooves of said short iron;

wherein said draft angle of said plurality of grooves is the angle measured between each wall of each groove of said plurality of grooves and a plane perpendicular to an outer surface of the striking face.

8. The golf club head of claim 7 , wherein said draft angle of said plurality of grooves of said mid iron is greater than said draft angle of said plurality of grooves of said long iron.

9. The golf club head of claim 7 , wherein said draft angle of said plurality of grooves of said mid iron is less than said draft angle of said plurality of grooves of said short iron.

10. The golf club head of claim 7 , wherein said plurality of grooves of each of said plurality of iron type golf club heads comprise a width, wherein said width of said plurality of grooves of said long iron is less than said width of said plurality of grooves of said short iron.

11. The golf club head of claim 10 , wherein said plurality of grooves of said mid iron is greater than said width of said plurality of grooves of said long iron.

12. The golf club head of claim 7 , wherein said plurality of grooves of each of said plurality of iron type golf club heads comprise a groove pitch measurement, wherein said groove pitch of said plurality of grooves of said long iron is greater than said groove pitch of said plurality of grooves of said mid iron.

13. The golf club head of claim 12 , wherein said plurality of grooves of each of said plurality of iron type golf club heads comprise a groove pitch measurement, wherein said groove pitch of said plurality of grooves of said short iron is greater than said groove pitch of said plurality of grooves of said mid iron.

14. A set of iron type golf club heads, comprising:

a plurality of iron type golf club heads, said plurality of iron type golf club heads comprising a long iron having a loft angle greater than or equal to 15 degrees and less than 26 degrees, a mid iron having a loft angle greater than or equal to 26 degrees and less than 37 degrees, and a short iron having a loft angle greater than or equal to 37 degrees and less than 47 degrees;

wherein each of said plurality of iron type golf club heads comprise a striking face, and wherein each of said plurality of iron type golf club heads comprise a plurality of grooves formed in said striking face extending generally from a heel side of said striking face towards a toe side of said striking face;

wherein said plurality of grooves of each of said plurality of iron type golf club heads comprise an edge radius, wherein said edge radius of said plurality of grooves of said long iron is greater than said edge radius of said plurality of grooves of said short iron;

wherein said edge radius of said plurality of grooves is the radius of the edge at the intersection of a wall of each groove of said plurality of grooves and an outer surface of the striking face;

wherein said edge radius of said plurality of grooves of said mid iron is greater than or equal to 0.005″ and less than or equal to 0.007″.

15. The golf club head of claim 14 , wherein said edge radius of said plurality of grooves of said mid iron is greater than said edge radius of said short iron.

16. The golf club head of claim 14 , wherein said edge radius of said plurality of grooves of said mid iron is less than said edge radius of said long iron.

17. The golf club head of claim 14 , wherein said edge radius of said plurality of grooves of said short iron is less than 0.005″.

18. The golf club head of claim 17 , wherein said edge radius of said plurality of grooves of said long iron is greater than or equal to 0.007″ and less than or equal to 0.020″.

19. The golf club head of claim 14 , wherein said edge radius increases through said set of iron type golf club heads in a substantially linear relationship as said loft of each of said plurality of iron type golf club heads decreases.
