The KING F6 Irons set with graphite shafts feature progressive construction throughout the set, allowing you to hit the longer irons as easily as you can hit a wedge.
This gorgeous iron set features TecFlo construction, which is a progressive way of engineering the clubs to make them all easier and more forgiving. There is a full hollow design in the longer irons (4i-5i), a half hollow design in the mid irons (6i-7i), and a cavity back design in the scoring irons (8i-GW).
There is a ton of technology packed into these irons; the Speed Channel sole and face are designed to minimize off-center hits, and the CNC milled grooves provide increased control and feedback. Engineered aluminum cap replaces steel on half hollow irons which frees up 5g of discretionary weight which has been replaced lower and further back in the head.
