Abstract
Embodiments of grooves of golf club heads and methods to manufacture grooves of golf club heads are generally described herein. Other embodiments may be described and claimed.
Claims20
A golf club head comprising:
- a non-hollow body having a club face to engage a golf ball;
- and
- at least one groove having a variable depth and extending a length between a first end and a second end of the club face,
- wherein the variable depth comprises a first depth associated with a first depth portion and a second depth associated with a second depth portion, the first depth being greater than the second depth, the first depth portion extending from a location between the first end and the center to a location between the second end and the center, the second depth portions having same depths and extending between the first end and the first depth portion and extending between the second end and the first depth portion,
- wherein a greatest depth of the at least one groove is between the first end and the second end and is at least partly offset relative to a center of the length,
- wherein first depth portion has the same de th as the greatest depth,
- wherein the depths of the second depth portions are less than the greatest depth, and
- wherein the first depth portion extends less than half of the length of the at least one groove.

A golf club head comprising:
- a club face to engage a golf ball;
- and
- at least one variable depth groove having a heel end and a toe end defining a length of the groove,
- wherein a greatest depth of the at least one groove is between the heel end and the toe end and is at least partly offset relative to a center of the length, is offset relative to the first end and is offset relative to the second end.
1 more element
A golf club head comprising:
- a club face to engage a golf ball;
- at least one groove having a heel end and a toe end defining a length of the groove, a center of the groove being defined by a center of the length;
- wherein at least a portion of a bottom surface of the groove between the heel end and the center is convex relative to the club face and faces away from the heel end and faces generally toward the toe end, or wherein at least a portion of the bottom surface of the groove between the toe end and the center is convex relative to the club face and faces away from the toe end and faces generally toward the heel end.
A method of forming a club head comprising:
- providing a club face to engage a golf ball;
- and
- forming at least one variable depth groove having a heel end and a toe end defining a length of the groove,
- wherein a greatest depth of the at least one groove is between heel end and the toe end and is at least partly offset relative to a center of the length, is offset relative to the first end and is offset relative to the second end.
