       15 . The putter type golf club head of  claim 1  wherein said bar members extend rearwardly divergent to each other.  
   
   
       16 . The putter type golf club head of  claim 1  wherein said bar members extend rearwardly convergent to each other.  
   
   
       17 . A putter type golf club head including a club head body and means for attachment to a golf shaft, said club head body formed of a material having a first weight, said club head body including a frontal ball string face having a center of percussion thereon, a rear face, a heel, toe, top ridge, and bottom sole, said club head body further including a rear cavity formed by a heel mass and toe mass, wherein the improvement comprises: a pair of longitudinal, geometrically shaped, weighted bar members, each bar having only a proximal end attached to said rear face and a free distal end extending rearwardly from said rear face; one of said bar members being located on the heel side of said center of percussion and a second of said bar members being located on the toe side of said center of percussion, said bar members extending through said rear cavity between the heel mass and the toe mass in a rearward direction perpendicular to said ball striking face; said bar members being formed with a material having a second weight heavier than said material having a first weight.  
   
   
       18 . The putter type golf club head of  claim 17  wherein said bar members are formed with adjustable weights.  
   
   
       19 . The putter type golf club head of  claim 17  wherein said bar members are further defined by a hollow interior and form a housing for a cooperating weight located therein.  
   
   
       20 . The putter type golf club head of  claim 19  wherein each said cooperating weight is adjustable in size to permit adjustment of the overall weight of each of said bar members.
