Abstract: In a putter, at least one adjustable weight is provided which can be moved to different positions longitudinally along the putter head. The putter head is provided with a open channel with closed ends. The weight is slidably mounted within said outer chamber with bolts extending through a slot into a slide within the channel, and the bolt is adapted to be screw tightened into said slide to hold said weight in position. A vibration damping plate is disposed between the weight and the putter head. The front face of the putter is provided parallel vertical grooves defined in the front face, and the grooves are separated by flat lands between The grooves are arcuate in cross section so that the sidewalls of the groove slope is at an angle substantially less that perpendicular to the lands.
