This famous shape is the # 12. It originated in the early 70's and is a classic. One of the very first to have a curved top line to match the rocker sole. This effect always made the putter seem to set perfectly behind the golf ball even on greens that have a lot of undulation. This shape has won numerous tour events and continues to be a very popular model. The piece shown has a "kick back" type hosel which allows the putter to have a near face balance effect. Made in 1030 carbon and 304 stainless steel.
