1. A method of producing a high backspin golf club, which minimizes golf ball cover damage comprising the steps of:
providing a golf club head, having a club face;
placing a least one groove onto said club face; and,
shaping at least one of said at least one groove to form:
a first surface connected to the club face via a chamfered edge that forms a fourth substantially flat surface;
a second surface connected to the club face;
a third surface that extends between the first surface and the second surface, wherein the first surface faces the second
surface; a leading edge formed by the substantially flat fourth surface and the leading edge between said groove and said
club face is an obtuse angle to reduce cover damage.
