Abstract
A putter with a putter head that has a rear hollow cavity enclosed within the putter head body to help move the center of gravity forward and a shaft axis that intersects the center of gravity of the putter head within a predetermined range is disclosed. The putter head may have a heel counterweight to move the center of the gravity of the putter head to the desired direction. The hollow cavity in the putter head may extend from a heel region to the toe region of the putter head. In some examples, the hollow cavity may comprise a plurality of hollow cavities or may be a single cavity located in the heel region or the toe region.
