Multi Metal Combination

The soft carbon steel S20C frame is precisely forged into three steps giving it an extra ‘Pocket Cavity’ area. The saved weight is re-distributed to the toe and heel with tungsten weights to expand the effective hitting area. A high-resilient special steel SUP-10 face set into the frame provides a solid and responsive impact feel.
 

Progressive Face Design

The 3-step face for #4-#7, forged thicker in the center part and thinner step-by-step toward the perimeter, accelerates the ball speed at impact. The 2-step face for #8-PW transfers the impact power to the ball without loss and enables better ball control. AW and SW are made of forged soft carbon steel for better control with a soft feel.
