This is a Karsten I blade-type putter, named after Karsten Solheim, the founder of PING. This is the putter that became the prototype for later commemorative models. This is an early, non-R, long-step model, of which very few were produced, and it's in excellent condition. A rare item for PING collectors. While R-stamped, short-step versions exist, the original condition of the early type is rarely seen. Please review the images before considering a purchase. The catalog is for explanatory purposes only and is not included. This item was produced over 50 years ago. Due to its used condition, please understand that no returns or refunds are accepted.
