Uniquely tuned to produce a sound (or feel) to match the power inside every iron
Center of gravity location in each head is precision-placed to optimize long, middle and short-iron flight
Inverted Cone Technology promotes faster ball speed on mis-hits for consistent distance
Each iron is individually engineered to promote distance and uniform distance gaps
Multi-functional sole lowers the center of gravity and reduces turf-drag to make it easy to launch shots high and long
Every individual iron boasts a different face thickness - the thinnest and fastest occur in the long irons, with the face in each successive iron growing thicker down through the middle- and short irons
New groove design which conforms to the USGA rules of competition
