1. A golf club head comprising:
- a body having a heel portion, a toe portion, a sole portion, and an outer surface;
a strikeface having a geometric center;
a head center of gravity; and
a weight member including a weight pad and a weight member axis through a geometric center of the weight member running longitudinally and symmetrically dividing a width of the weight member along the entire length, whereinthe weight member comprises opposing first and second ends;
the weight member is configured to be positioned adjacent to the sole portion of the club head, substantially flush with the outer surface of the body,the weight member is repositionable by the user to a first position or a second position,the weight member axis of the weight member is aligned with a z-axis extending through the head center of gravity from the strikeface to a rear portion of the club head, anda center of gravity of the weight pad is positioned offset from the weight member axis, and comprises a weight pad axis, the weight pad axis extends between a position of the weight pad center of gravity when the weight member is in the first position and the position of the weight pad center of gravity when the weight member is in the second position, wherein the weight pad axis forms a weight pad angle relative to the weight member axis ranging from 5 to 20 degrees, whereinthe weight pad is positioned closer to the heel end than the toe end relative to the weight member axis when the weight pad is in the first position,the weight pad is positioned closer to the toe end than the heel end relative to the weight member axis when the weight pad is in the second position,the club head having the weight member in the first position shifts the head center of gravity toward the strikeface, andthe club head having the weight member in the second position shifts the head center of gravity away from the strikeface, such that on impact with a golf ball at the geometric center of the strikeface, the club head having the weight member in the first position applies a first vertical spin on the golf ball and the club head having the weight member in the second position applies a second vertical spin on the golf ball such that the second vertical spin is different than the first vertical spin.

Abstract
A golf club head includes a body having a heel portion, a toe portion, a sole portion, and an outer surface, a strikeface having a geometric center, a head center of gravity, and a weight member including a weight pad. The weight member is configured to be repositionable by the user to a first position or a second position. The club head having the weight member in the first position shifts the head center of gravity toward the strikeface, and the club head having the weight member in the second position shifts the head center of gravity away from the strikeface.

16. A golf club head comprising:
-
a body having a heel portion, a toe portion, a sole portion, and an outer surface; a strikeface having a geometric center; a head center of gravity; and a weight member having opposing first and second edges and including a weight member axis and a geometric center, the weight member axis intersecting the first and second edges and the geometric center, the weight member axis runs longitudinally and symmetrically dividing a width of the weight member along the entire length, the weight member axis of the weight member is aligned with a z-axis extending through the head center of gravity from the strikeface to a rear portion of the club head, wherein a width of the weight member in a direction taken orthogonal to the weight member axis increases along the weight member axis from the geometric center towards the first and second edges;
whereinthe weight member comprises a weight pad with a center of gravity, wherein the center of gravity of the weight pad is positioned offset from the weight member axis, the weight pad comprises a weight pad axis, wherein the weight pad axis forms a weight pad angle relative to the weight member axis ranging from 5 to 20 degrees, wherein the weight pad is positioned closer to the heel end than the toe end relative to the weight member axis when the weight pad is in the first position, the weight pad is positioned closer to the toe end than the heel end relative to the weight member axis when the weight pad is in the second position, and wherein the weight pad axis extends between a position of the weight pad center of gravity when the weight pad is in the first position and the position of the weight pad center of gravity when the weight pad is in the second position. - View Dependent Claims (17, 18, 19)
