Diamond Face VFT on Military Grade Steel Face
Behind the face of the Tour Edge C722 Irons lies Tour Edge's Diamond Face VFT. This inserts 92 Diamond shapes ranging in thickness behind the face to create "mini-trampolines" that boost ball speed across more area of the face. The Diamond VFT is wrapped within a Military Grade Steel face, a material used in aerospace, to increase face flex across more surface area of the face.
