The Titleist 712 CB irons are made for the skilled player as a more playable alternative to the MB irons. These irons have a cavity with a muscle within that cavity. This combines the higher Moment of Inertia that comes from a cavity back and the feel and control that comes with a traditional muscleback. The short blade length and minimal offset help give the player control over trajectory and overall shot shape. The sole is slightly wider to help improve turf interaction. The thin topline, rounded shape and satin finish give these clubs a great look to go with their great performance.
