A putter golf club that resists twisting by increasing the rotational inertia of the golf club to the maximum degree possible by distributing mass away from the center of mass of the putter, and thereby expands the sweet spot of the putter. Rotational inertia is maximized via use of a heel control wing and a toe control wing extending rearwardly and outwardly from a striking face of the putter as well as a tail rod extending perpendicularly from striking face. Further increase of rotational inertia is accomplished via s symmetrical recesses incorporated into heel and toe control wing.
