an elongated neck fixed to and extending from said top surface and including a hosel with said hosel fixed at an angle to said sole and positioned forward of said face;
said hosel having an opening for receiving a putter shaft;
said head having a thickness between said face and back surfaces that varies in the heel and toe regions from a maximum at the sole to a minimum at the top surface, and a thickness in a central region of less than 20% of the thickness in the heel and toe regions;
said sole having a thickness in said central region of less than about 20% of the thicknesses in said heel and toe regions;
said sole having a cut out region extending from said back surface toward said face;
said cut out region having parallel recessed edges; and

Abstract
A golf putter having a replaceable sole insert for varying putter head weight distribution along the length of the face. The putter has relatively thin face and sole central regions, with much thicker and heavier heel and toe regions. The central region of the sole is cut out. The cut out area has two opposite parallel recessed edges extending away from the back of the putter towards the face. An insert is configure to fit in the cut out area, with edges of the insert engaging the recessed edges to retain the insert in place. The sole may be flat or radiused, and the insert may have a lower surface corresponding to the sole. A neck connects the putter head to a shaft receiving hosel. The hosel has an outer end that is cut at an angle corresponding to the upper surface of the putter.
