An extreme 360° undercut cavity creates a large, thin, unsupported face that increases both speed and launch for more distance. High density tungsten drives the center of gravity low allowing stronger lofts to create even more speed and more distance.

Forgiveness

The use of extreme high density tungsten moves weight to the perimeter increasing moment of inertia for speed on off-center hits. 716 AP1 irons are the most forgiving among irons of similar size.
