Abstract

Some embodiments include a first golf club head and a second golf club head. The first golf club head includes a body having a face portion, and the second golf club head includes a body having a face portion. Meanwhile, the first club face portion comprises a face surface and at least one first club groove, and the second club face portion comprises a face surface and at least one second club groove. An edge radius of the first club head groove(s) can be less than an edge radius of the second club head groove(s), a base width of the first club head groove(s) can be less than a base width of the second club head groove(s), and/or a sidewall angle of the first club head groove(s) can be greater than a sidewall angle of the second club head groove(s). Other embodiments of related club heads and methods are also disclosed.

First claim

What is claimed is:

a second golf club head comprising:
a second club head body comprising a second club face portion;

wherein:
the first club face portion comprises a first club face surface and multiple first club grooves;
each first club groove, respectively, of the multiple first club grooves comprises a first club groove base, a first club groove sidewall adjacent to the first club groove base, a first club groove length dimension, a first club groove central axis approximately perpendicular to the first club groove base, and a first club groove cross sectional area approximately perpendicular to the first club groove length dimension and intersecting the first club groove central axis;
the first club groove central axis of at least two first club adjacent grooves of the multiple first club grooves are spaced apart by a first club groove pitch;
the first club groove base comprises a first groove base width;
the first club groove sidewall forms a first club groove sidewall angle;
the second club face portion comprises a second club face surface and multiple second club grooves;
each second club groove, respectively, of the multiple second club grooves comprises a second club groove base, a second club groove sidewall adjacent to the second club groove base a second club groove length dimension, a second club groove central axis approximately perpendicular to the second club groove base, and a second club groove cross sectional area approximately perpendicular to the second club groove length dimension and intersecting the second club groove central axis;
the second club groove central axis of at least two second club adjacent grooves of the multiple second club grooves are spaced apart by a second club groove pitch;
the second club groove base comprises a second groove base width;
the second club groove sidewall forms a second club groove sidewall angle;
the first club groove base width is less than the second club groove base width;
the first club groove sidewall angle is greater than the second club groove sidewall angle; and
a first ratio of the first club groove cross sectional area to the first club groove pitch is approximately equal to a second ratio of the second club groove cross sectional area to the second club groove pitch.

2. The set of golf club heads of claim 1 wherein:
the first golf club head comprises a first club loft angle greater than or equal to approximately 45 degrees; and
the second golf club head comprises a second club loft angle less than approximately 45 degrees.

3. The set of golf club heads of claim 1 wherein:
the first golf club head comprises a first club loft angle greater than or equal to approximately 47 degrees; and
the second golf club head comprises a second club loft angle less than approximately 47 degrees.

4. The set of golf club heads of claim 1 wherein:
each first club groove of the multiple first club grooves comprises a first club groove edge point and a first club groove edge radius at the first club groove edge point; and
the first club groove edge radius is greater than or equal to approximately 0.007 centimeter and less than or equal to approximately 0.026 centimeter.

5. The set of golf club heads of claim 1 wherein:
the first groove base width is greater than or equal to approximately 0.0350 centimeter and less than or equal to approximately 0.0414 centimeter.

6. The set of golf club heads of claim 1 wherein:
the first club groove sidewall angle is greater than or equal to approximately 21 degrees and less than or equal to approximately 27 degrees.

7. The set of golf club heads of claim 1 wherein:
each first club groove of the multiple first club grooves comprises a first club groove depth measured between the first club face surface and the first club groove base; and
the first club groove depth of each first club groove, respectively, of the multiple first club grooves is approximately the same.

8. The set of golf club heads of claim 7 wherein:
the first club groove depth is approximately 0.04 centimeter.

9. The set of golf club heads of claim 1 wherein:
each first club groove of the multiple first club grooves comprises a first club groove depth measured between the first club face surface and the first club groove base;
each second club groove, respectively, of the multiple second club grooves comprises a second club groove depth measured between the second club face surface and the second club groove base; and
the first club groove depth is approximately equal to the second club groove depth.

10. The set of golf club heads of claim 9 wherein:
the first club groove depth is approximately 0.04 centimeter.

11. The set of golf club heads of claim 1 wherein:
each first club groove of the multiple first club grooves comprises a first club groove edge point depth measured approximately parallel to the first club groove central axis and between a first club groove edge point and the first club face surface; and
the first club groove edge point depth is approximately 0.004 centimeter.

12. The set of golf club heads of claim 1 wherein:
each first club groove of the multiple first club grooves comprises a first club groove edge point width measured approximately perpendicular to the first club groove central axis and between a first club groove edge point and the first club groove central axis; and
