Golf club sole configuration

A golf club having a sole comprising a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club and a positive bounce crescent surface positioned between the bottom crescent surface and a leading edge of the sole and heel and toe sole surfaces.

A golf club having a sole comprising a crescent-shaped positive bounce surface and a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club wherein the club has a loft of greater than about 45° and a primary point located at a position that is vertically below an intersection of a plane that extends from the leading edge and a perpendicular line through the face approximately 0.55 inch from the leading edge in the middle of the club between the heel and toe, the positive bounce surface being between the leading edge and the bottom surface.

A set of golf clubs having a sole comprising a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club, wherein each of the golf clubs has a primary point being the most forward point on the front border that is located substantially below an intersection of a horizontal plane through the leading edge and a line perpendicular to the front face approximately 0.55 inch from the leading edge.

A set of golf clubs having a sole comprising a bottom surface is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club wherein each of the golf clubs has a primary point being the most forward point on the front border that is located substantially below an intersection of a horizontal plane through the leading edge and a line perpendicular to the front face at a 4th score line thereon.

A set of golf clubs having a sole comprising a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club, wherein each of the clubs has a crescent-shaped bounce surface between the bottom surface and the leading edge and having a bounce angle between about 12° and 15°.

A set of golf clubs having a sole comprising a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club, wherein each of the clubs has a crescent-shaped bounce surface between the bottom surface and the leading edge and having a bounce angle that increases through the set with an increase in iron loft.

A set of golf clubs having a sole comprising a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club, wherein each of the clubs is configured such that a line perpendicular to the face at 0.55 inch from the leading edge extends through the bottom crescent surface 17.

A set of golf clubs having a sole comprising a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club, wherein each of the clubs has a crescent-shaped bounce surface between the bottom surface and the leading edge and having a bounce angle that decreases with the loft of the club through the set.

A set of golf clubs having a sole comprising a bottom surface that is substantially planar with the ground when addressed by a player, the bottom surface being crescent-shaped with a back border being substantially straight and being substantially adjacent to a trailing edge of the sole and a front border extending toward the leading edge of the club, wherein each of the clubs has a crescent-shaped bounce surface between the bottom surface and the leading edge and having a substantially constant bounce angle.
