What is claimed is: 
     
         1 . A putter hand grip comprising:
 an upper hand grip comprising an
 elongated body of substantially uniform diameter along the length, having an upper end and a lower end with a central opening at the lower end to be slidable over the upper end of a putter shaft; wherein the lower end of the putter hand grip comprises at least one three-dimensional gripping structure. 
   
     
     
         2 . The putter hand grip of  claim 1  wherein the three-dimensional gripping structure comprises a hemisphere. 
     
     
         3 . The putter hand grip of  claim 1  wherein the three-dimensional gripping structure comprises a rounded taper. 
     
     
         4 . The putter hand grip of  claim 1  wherein the three-dimensional gripping structure comprises a spherical cap. 
     
     
         5 . The putter hand grip of  claim 1  wherein the three-dimensional gripping structure comprises an ellipsoidal cap. 
     
     
         6 . The putter hand grip of  claim 1  further comprising:
 a lower hand grip disposed a distance from the upper hand grip, wherein the upper hand grip is a shape selected from the group consisting of a hemisphere, a spherical cap, a rounded taper, and an ellipsoidal cap, wherein the lower hand grip is a shape having an upper rounded taper and a lower rounded taper. 
 
     
     
         7 . A putter hand grip comprising:
 an upper hand grip comprising an   elongated body having a length, an upper end, and a lower end with a central opening at the lower end slidable over the upper end of a putter shaft; wherein the lower end of the putter hand grip comprises at least one three-dimensional gripping structure.   
     
     
         8 . The putter hand grip of  claim 7  wherein the elongated body comprises a reverse taper. 
     
     
         9 . The putter hand grip of claim of  claim 7  wherein an upper cross-section of the upper hand grip comprises a semi-circle and a rectangular prism. 
     
     
         10 . The putter hand grip of  claim 9  wherein a lower of portion of the rectangular prism comprises a rounded taper. 
     
     
         11 . A method of swinging a putter comprising
 providing a golf putter comprising a shaft, a putter head, a upper hand grip, and a lower hand grip, wherein the upper hand grip is disposed around the shaft, wherein the lower hand grip is disposed around the shaft,   wherein the lower hand is grip disposed a distance from the upper hand grip, wherein the upper hand grip is a shape selected from the group consisting of a hemisphere, a spherical cap, a rounded taper, and an ellipsoidal cap, wherein the lower hand grip is a shape having an upper rounded taper and a lower rounded taper;   placing a first hand on the upper hand grip;   placing a second hand on the lower hand grip; and   swinging the putter towards a golf ball.
