There is disclosed a golf putter head which is longer (5.5 inches or greater), wider (at least 1.30 inch), and higher (at least 1.375 inch) than a conventional putter head so that the putter head is easier to align initially and provides greater distance and control during putting. The putter head includes a blade having a striking face, a blade sole, a heel end, a toe end, and a rear face. A flange extends integrally and rearwardly from the blade and has enlarged heel and toe sections and reduced-thickness center portion forming a cavity behind the putter blade. The center section of the flange is between 0.125 and 0.375 inch in thickness to provide reinforcement against vibration to the thin blade. As a result of the mass distribution of the blade and flange, the center of mass is positioned vertically to coincide with the center of a golf ball being stroked, and the putter has a rotational moment of inertia about a vertical axis through the center of mass of greater than 5000 gm/cm2. The putter head is cast of aluminum and weights between 265 and 330 grams. The putter head has a milled face smoothed to within 0.001 inch to eliminate skew on striking.

A golf putter head which weighs between 265 and 330 grams and has a center of mass comprising: (a) a blade a striking face, a blade sole, a heel end, a toe end, and a rear face wherein the blade has a width, a height greater than the radius of a standard golf ball, and a length of 5.5 inches or greater; (b) a hosel attached to the blade; (c) a flange having a top surface and a flange sole and integrally extending rearwardly from the blade adjacent the blade sole wherein the blade sole and the flange sole form a putter sole and the flange has a length equal to the length of the blade and a width greater than the width of the blade and such that the combined width of the blade and flange is at least 1.30 inch and wherein the flange has a reduced thickness center portion to create a cavity behind the blade and increased thickness portions adjacent the heel and toe of the blade, wherein the mass of the head is distributed to establish a locus for the center of mass approximately one half way along the length of the blade and along the height of the blade at a vertical distance from the sole which when the putter head is raised for putting above a putting surface the center of mass is aligned vertically with a center of a standard golf ball resting on the putting surface and to establish a rotational moment of inertia about the center of mass greater than 5000 gm. cm.2.
