Abstract

Embodiments of golf clubs with grooves and methods of manufacture thereof are described herein. Other embodiments and related methods are also disclosed herein.

First claim

What is claimed is:

1. A golf club head comprising:
a body having a strike face with channels;
and at least one insert located within at least one of the channels, wherein:
the at least one of the channels comprises a single groove; and
the at least one insert forms at least a portion of the single groove;
a radius of an exterior edge of the single groove is partially formed by the at least one insert and is also partially formed by the strike face;
the at least one insert is asymmetrical about a first axis; and extending into the groove and away from the strike face, and
the first axis is substantially perpendicular to a width of the at least one of the channels.

2. The golf club head of claim 1 , wherein:
at least a portion of the at least one of the channels forms a different portion of the single groove.

3. The golf club head of claim 1 , wherein: the at least one insert is a single piece.

4. The golf club head of claim 1 , wherein: the at least one insert comprises at least two inserts; each of the at least two inserts forms different portions of the single groove; and the at least portion of the single groove comprises different portions of the single groove.

5. The golf club head of claim 1 , wherein: the at least one insert is permanently affixed within the at least one of the channels.

6. The golf club head of claim 1 , wherein: the at least one insert is removable and replaceable.

7. The golf club head of claim 1 , wherein: the strike face comprises a first material; and the at least one insert comprises a second material different from the first material wherein the second material is softer than the first material.

8. The golf club head of claim 1 , wherein: the at least one of the channels comprises a first cross section; the single groove comprises a second cross section; the first cross section comprises a first cross-sectional area; the second cross section comprises a second cross-sectional area; and the second cross-sectional area is non-proportional to the first cross-sectional area.

9. The golf club head of claim 1 , wherein: the at least one of the channels comprises a first cross section; the single groove comprises a second cross section; the first cross section comprises a first cross-sectional area; the second cross section comprises a second cross-sectional area; and the second cross-sectional area is substantially proportional to the first cross-sectional area.

10. The golf club head of claim 1 , wherein: the at least one of the channels is asymmetrical about the first axis; and the single groove is symmetrical about the first axis.

11. The golf club head of claim 1 , wherein: the at least one of the channels is symmetrical about the first axis; and the single groove is symmetrical about the first axis.

12. The golf club head of claim 1 , wherein: the at least one of the channels comprises a first cross section; the at least one insert comprises a second cross section; the single groove comprises a third cross section; the first cross section comprises a first cross-sectional area; the second cross section comprises a second cross-sectional area; the third cross section comprises a third cross-sectional area; and the first cross-sectional area is approximately equal to a sum of the second and third cross-sectional areas.

13. The golf club head of claim 1 , wherein: the at least one of the channels comprises a first cross section; the at least one insert comprises a second cross section; the single groove comprises a third cross section; the first cross section comprises a first cross-sectional area; the second cross section comprises a second cross-sectional area; the third cross section comprises a third cross-sectional area; and the first cross-sectional area is greater than a sum of the second and third cross-sectional areas.

14. The golf club head of claim 13 , further comprising: an adhesive in the at least one of the channels; wherein: the first cross-sectional area is approximately equal to a sum of the second cross-sectional area, the third cross-sectional area, and a fourth cross-sectional area; the fourth cross-sectional area is a portion of the first cross-sectional area; and the adhesive is located within at least a portion of the fourth cross-sectional area.

15. The golf club head of claim 1 , wherein: the at least one of the channels and the at least one insert are coupled together by a friction fit.

16. The golf club head of claim 1 , wherein: the insert is not located above a top surface of the strike face; and the insert is not substantially planar to the strike face.
