METAL WOOD CLUB
A golf club head is provided with a body that has an address position with a zero degree bounce portion on the sole and a center sole position with a multi-relief surface of the sole having a negative bounce portion. The negative bounce portion may comprise a negative 0.5 to a negative 4.0 degree surface. In one embodiment, the multi-relief surface may comprise the negative bounce portion and a cutaway portion extending to the back of the sole, which may have a depth of about 0.05 to 0.5 inch from a regular sole surface. In another embodiment, the golf club head includes a weight system to adjust the center of gravity. In one embodiment, the weight system is a tube having a weight at one end that may be inserted into the golf club head to move the center of gravity at least forward and backward within 6 mm and up and down within 6 mm. Preferably, the tube is angled downward toward the face by at least 3 degrees.
1 . A golf club head, the golf club head comprising:
a body having a face, a sole, a crown, and a skirt joining the face, sole, and crown, the body having a heel end and a toe end,
wherein the golf club head yields a difference in a shaft angle and a difference in a face angle of the golf club head when the golf club head is at an address position compared to when the golf club head is at an impact position.
2 . The golf club head of claim 1 , wherein the difference in the shaft angle is greater than about 5 degrees and less than about 10 degrees.
3 . The golf club head of claim 2 , wherein the shaft angle at the address position is about 45 degrees to about 55 degrees.
4 . The golf club head of claim 2 , wherein the shaft angle at the impact position is about 55 degrees to about 60 degrees.
5 . The golf club head of claim 1 , wherein the body further comprises;
a negative bounce portion on the sole of the golf club head near the face of the golf club head; and
a cutaway portion at least partially adjacent to the rear of the negative bounce portion of the sole,
wherein the cutaway portion has a different bounce angle than the negative bounce portion and wherein the cutaway portion forms a depression on the sole of the golf club head, and
wherein the cutaway portion has a depth of about 0.05 to about 0.50 inches.
6 . The golf club head of claim 5 , wherein the negative bounce portion has a constant angle.
7 . The golf club head of claim 6 , wherein the negative bounce portion comprises a negative bounce angle of between about 0.5 degrees to about 4.0 degrees.
8 . A golf club head, the golf club head comprising:
a body having a face, a sole, a crown, and a skirt joining the face, sole, and crown, the body having a heel end and a toe end,
wherein the body has an address position further comprises;
a negative bounce portion on the sole of the golf club head, and
a cutaway portion at least partially adjacent to the rear of the negative bounce portion,
wherein the negative bounce portion and the cutaway portion yields a difference in a shaft angle and a difference in a face angle when the golf club head is at an address position compared to when the golf club head is at an impact position.
9 . The golf club head of claim 8 , wherein the difference in the shaft angle is greater than about 5 degrees and less than about 10 degrees.
10 . The golf club head of claim 9 , wherein the shaft angle at the address position is about 45 degrees to about 55 degrees.
11 . The golf club head of claim 9 , wherein the shaft angle at the impact position is about 55 degrees to about 60 degrees.
12 . The golf club head of claim 10 , wherein the negative bounce portion has a constant angle along an entire length.
13 . The golf club head of claim 12 , wherein there is a step in depth at a boundary between the negative bounce portion and the cutaway portion.
14 . A golf club head, the club head comprising:
a body having a face, a sole, a crown and a skirt joining the face, sole and crown, the body having a heel end and a toe end,
wherein when the toe end is up at least 5 degrees at a first measurement when the face measures square, and at a centered position a second measurement of the face measures different from the first measurement.
15 . The golf club head of claim 14 , wherein the face measures at least two degrees more open at the second measurement.
16 . The golf club head of claim 14 , wherein the body has an address position further comprising;
a negative bounce portion on the sole of the golf club head, and
a cutaway portion at least partially adjacent to the rear of the negative bounce portion.
17 . The golf club head of claim 16 , wherein the negative bounce portion has a constant angle along an entire length.
18 . The golf club head of claim 17 , wherein there is a step in depth at a boundary between the negative bounce portion and the cutaway portion.
