The standard Callaway Golf Steelhead X-16 Irons have a shorter blade length and wider topline than the X-14 Irons, with the benefit of Callaway Golf's new "Notch" weighting. This moves weight to the perimeter for a strong, confidence-enhancing look behind the ball. Each iron has a low center of gravity for strong trajectory and great forgiveness, a cambered sole for better turf interaction, and a soft satin finish with a contrasting, sandblasted hitting area.
