Abstract
A golf putter having a uniquely configured striking surface is claimed. The putter has a striking surface that is twisted between the toe of the putter and the heel of the putter. The loft angle associated with the striking surface of the putter varies from a positive loft angle near the heel to a negative loft angle near the toe. The striking surface of the putter has a midline. The striking surface is twisted about the mid-line. The plane of the twisted striking surface is also slightly curved to eliminate any concave curvatures created by the twist. A non-metallic insert is added to the striking surface. The non-metallic insert has thickness that varies as a function of its position along the mid-line.
Claims22
A putter head assembly, comprising:
- a putter body having a toe end, a heel end and a face surface that extends from said heel end toward said toe end, wherein said face surface has a loft angle configuration that varies between said heel end and said toe end;
- a non-metallic insert disposed in at least a portion of said face surface, wherein said non-metallic insert conforms to the loft angle configuration of said face surface.
A putter, comprising:
- a shaft having a first end and a second end;
- a handle grip coupled to said first end of said shaft;
- a putter head coupled to said second end of said shaft, said putter head including a face surface having a toe end and a heel end, said face surface being symmetrically disposed around an imaginary mid-line that extends from said toe end to said heel end, wherein said face surface is twisted about said mid-line creating a loft angle configuration that varies between said toe end and said heel end;
- a non-metallic insert disposed in at least a portion of said face surface, wherein said non-metallic insert conforms to the loft angle configuration of said face surface.
A golf club striking surface comprising:
- a contact face having a first end, a second end and an imaginary mid-line that runs down the center of said contact face between said first end and said second end, wherein said mid-line follows a curved path, having a predetermined radius of curvature, and said contact face is twisted around said mid-line;
- an insert disposed within said contact face, wherein said non-metallic insert has a thickness along said mid-line that varies as a function of position on said mid-line.
