Abstract

A golf putter ( 1 ) having, relative to its cross-sectional area in the horizontal plane (in use), a relatively small ground-contacting area; ( 2 ) wherein the putter head is made of different materials, wherein one material is relatively dense and constitutes the core of the head, including the ball-contacting face, and another material is relatively less dense and constitutes the periphery of the head; ( 3 ) whose base is at an angle to the ground when the putter is held upright, whereby lying the base on the ground provides increased loft on the face of the putter; and/or ( 4 ) having, on its top side, extending normal to its face, an area of contrasting appearance defining an arrow in the line of the putt.

1 . A golf putter head having, relative to its cross-sectional area in a horizontal plane (in use), a relatively small ground-contacting area. 
     
     
         2 . A golf putter head that is made of different materials, wherein one material is relatively dense and constitutes a core of the head, including a ball-contacting face, and another material is relatively less dense and constitutes a periphery of the head. 
     
     
         3 . A golf putter head having, on its top side, extending normal to its face, an area of contrasting appearance defining an arrow in the line of a putt. 
     
     
         4 . The golf putter head, according to  claim 1 , wherein the ground-contacting area is at least 20% less than the cross-sectional area. 
     
     
         5 . The golf putter head, according to  claim 1 , whose base is at an angle to the ground when the putter is held upright, whereby lying the base on the ground provides increased loft on the face of the putter head. 
     
     
         6 . The golf putter head, according to  claim 5 , wherein the angle to the ground is 5 to 20°. 
     
     
         7 . The golf putter head, according to  claim 1 , that is made of different materials, wherein one material is relatively dense and constitutes a core of the head, including a ball-contacting face, and another material is relatively less dense and constitutes a periphery of the head. 
     
     
         8 . The golf putter head, according to  claim 1 , having, on its top side, extending normal to its face, an area of contrasting appearance defining an arrow in the line of a putt. 
     
     
         9 . The golf putter head according to  claim 2 , having, relative to its cross-sectional area in a horizontal plane (in use), a relatively small ground-contacting area. 
     
     
         10 . The golf putter head, according to  claim 9 , wherein the ground-contacting area is at least 20% less than the cross-sectional area. 
     
     
         11 . The golf putter head, according to  claim 9 , whose base is at an angle to the ground when the putter is held upright, whereby lying the base on the ground provides increased loft on the face of the putter head. 
     
     
         12 . The golf putter head, according to  claim 11 , wherein the angle to the ground is 5 to 20°. 
     
     
         13 . The golf putter head, according to  claim 2 , having, on its top side, extending normal to its face, an area of contrasting appearance defining an arrow in the line of a putt. 
     
     
         14 . The golf putter according to  claim 3 , having, relative to its cross-sectional area in a horizontal plane (in use), a relatively small ground-contacting area. 
     
     
         15 . The golf putter head, according to  claim 14 , wherein the ground-contacting area is at least 20% less than the cross-sectional area. 
     
     
         16 . The golf putter head, according to  claim 14 , whose base is at an angle to the ground when the putter is held upright, whereby lying the base on the ground provides increased loft on the face of the putter head. 
     
     
         17 . The golf putter head, according to  claim 16 , wherein the angle to the ground is 5 to 20°. 
     
     
         18 . The golf putter head according to  claim 3  that is made of different materials, wherein one material is relatively dense and constitutes a core of the head, including a ball-contacting face, and another material is relatively less dense and constitutes a periphery of the head.
