Description Constructed from high grade Carpenter C455 stainless. Although expensive this steel has phenomenal properties. 250% the tensile strength of the steels used by our competitors allows the walls to be made 60% thinner creating an ultra hot face – you will hear it. High strength-to-weight ratio allows weight to be redistributed to precise points giving the head a high moment of inertia creating a very forgiving club. The face of the club has been frequency matched to that of our Quantum golf ball to maximise distance.
