The Tour Authentic X-Forged irons feature a 1020 forged carbon steel head with tour-inspired styling for a classic look and feel. They also feature a ''Flighted Center of Gravity'' that produces higher flight in the long irons, and a lower, more controlled flight in the short irons for maximum playability. The Tour Authentic model has an increased bounce angle for smoother turf interaction, thin topline and minimal offset for a classic look and shot-shaping capability, narrow sole, and shorter blade length.
