The classic muscleback blade MP-18 is the flagship iron of the line and offers the traditional blade look along with great feel and workability. It has a slightly wider sole and more compact head than its predecessor, which makes it more forgiving without sacrificing the look at address. It is composed of 1025E pure carbon steel. The MP-18 is available in 3-PW (RH Only) and the stock shaft is the Dynamic Gold S300.
