Cobra Carbon CB irons. The King Cobra Forged Carbon CB irons are aimed at lower handicappers and feature a cavity back design with a transitioning muscle arch behind the hitting zone that gives you the ultimate in trajectory control. And since they're made with 8620 Carbon Steel, they offer incredible feel in addition to the workability you'd expect from a forged iron. They're also nickel-chrome plated for classic appearance and protection. Muscle arch transitions throughout the set forming a lower centre of gravity in the long irons and a higher centre of gravity in the shorter irons for a consistent controlled trajectory. There are some of the best feeling irons in Cobra's history.
