Abstract
Briefly, a putter head is provided that concentrates the weight of the putter head at the far ends of the heel and toe of the putter head. The putter head has an ultralight putter body that includes a putter face and a shank for attaching a putter shaft. The ultralight putter body has an axially aligned heel cavity and toe cavity that are constructed to receive weights. The heel weight and toe weights are very dense, and constructed to be received into the respective weight cavity of the light putter body. Due to the extreme concentration of weight at the fare ends of the heel and toe of the putter head, the putter face has exceptional rotational stability with a substantially larger sweet spot than known putter heads. The weights may be provided as changeable weight pairs, such that the overall weight and balance of the putter head may be adjusted, while maintaining the position of the sweet spot.
