A club head is configured such that the toe thickness is greater than the heel thickness in order to compensate for the toe-down look encountered, for example, in extended-length putters. In accordance with a further aspect of the present invention, the club head body in the heel region is weight-compensated to substantially balance with the toe region. In accordance with one embodiment, a bore configured to accept the shaft is provided at substantially the center of the top rail. In accordance with one embodiment, cut-out regions are provided in the back of the club head body in the toe region and the heel region to provide the required weight compensation.

The putter head of claim 1, wherein the first and second cavity have an upper cavity portion and a lower cavity portion. 3. The putter club head of claim 2, wherein the upper cavity portion has a radius of curvature substantially similar to the radius of curvature of the top surface. 4. The putter club head of claim 2, wherein the lower cavity portion has a radius of curvature substantially similar to the radius of curvature of the top flange surface. 5. The putter club head of claim 1, wherein the bottom flange surface has a radius of curvature substantially similar to the sole radius of curvature. 6. The putter club head of claim 1, wherein the flange extends outwardly from the back of the body a greater distance at the toe and the heel than the flange extends at the midpoint of the body. 7. The putter club head of claim 1, wherein the thickness of the flange is greater at the toe and heel, than at the midpoint of the body. 8. The putter club head of claim 1, wherein the hosel is a bore. 9. A putter club head comprising: a club head body having a toe; a heel; a sole having a sole radius of curvature; a front face; a top surface opposite the sole, the top surface being concave and having a radius of curvature, wherein the top surface radius of curvature is greater than the sole radius of curvature; a back opposite and parallel to the front face; a hosel coupled to the top surface and configured to accept a shaft, wherein the shaft connects to the hosel at substantially a midpoint of the top surface, wherein the midpoint of the top surface comprises the intersection of the midpoint measured form the front face to the back, and from the toe to the heel; wherein the toe that extends from the sole to the top surface is thicker than the heel that extends from the sole to the top surface; a first cavity adjacent the toe that extends into the club head body from the back towards the front face; a second cavity adjacent the heel that extends into the club head body from the back towards the front face; wherein the first cavity extends into the body from the back towards the front face a greater distance than the second cavity; the first cavity has a volume greater than a volume of the second cavity, wherein the first cavity and the second cavity have an upper cavity portion and a lower cavity portion, and the upper cavity portion has a radius of curvature substantially similar to the radius of curvature of the top surface; wherein the club head body has a center of gravity along a shaft axis defined by a hosel; and wherein the club head body at the heel is weight compensated such that the center of gravity of the club head body lies on the shaft axis. 10. The putter club head of claim 9, further comprising a flange, having a top flange surface and a bottom flange surface, extending outwardly from the back of the body, continuously along the length of the body, from the toe to the heel, adjacent the sole, wherein the flange has a thickness extending from the sole to the bottom portion of the first cavity and second cavity. 11. The putter club head of claim 10, wherein the bottom flange surface has a radius of curvature substantially similar to the sole radius of curvature. 12. The putter club head of claim 10, wherein the thickness of the flange is greater at the toe and heel, than at the midpoint of the body. 13. The putter club head of claim 10, wherein the flange extends outwardly from the back of the body a greater distance at the toe and the heel then the flange extends at the midpoint of the body. 14. The putter club head of claim 13, wherein the top surface at the toe end comprises a greater distance from a ground plane when the club head is at an address position than the top surface at the heel end. 15. The putter club head of claim 9, wherein the lower cavity portion has a radius of curvature substantially similar to the radius of curvature of the top flange surface. 16. The putter club head of claim 9, wherein the hosel is a bore. 17. A method for manufacturing a putter club head comprising: forming a club head body having a toe, a heel, a sole having a sole radius of curvature, a front face, a top surface opposite the sole, the top surface being concave and having a radius of curvature, greater than the sole radius of curvature, and a back opposite and parallel to the front face; providing a hosel coupled to the top surface, wherein the hosel is configured to accept a shaft, wherein the shaft connects to the hosel at substantially a midpoint of the top surface, wherein the midpoint of the top surface comprises the intersection of the midpoint measured form the front face to the back, and from the toe to the heel; providing the toe to extend from the sole to the top surface and to be thicker than the heel that extends from the sole to the top surface; providing a first cavity adjacent the toe that extends into the body from the back towards the front face; providing a second cavity adjacent the heel that extends into the body from the back towards the front face, wherein the first cavity extends into the body from the back towards the front face a greater distance than the second cavity; providing the first cavity to have a volume greater than the volume of the second cavity; and providing a flange, having a top flange surface and a bottom flange surface, to extend outwardly from the back of the body, continuously along the length of the body, from the toe to the heel, adjacent the sole, wherein the flange has a thickness extending from the sole to the bottom portion of the first cavity and second cavity; wherein the club head body has a center of gravity along a shaft axis defined by a hosel; and wherein the club head body at the heel is weight compensated such that the center of gravity of the club head body lies on the shaft axis. 18.
