Elongated blade length, combined with a horizontal center of gravity perfectly positioned in the center of the club face results in higher quality shots on off center hits.
Moderately low actual vertical cg (center of gravity) produces the medium to high trajectories desired by many levels of players.
Undercut cavity design forces the center of gravity rearward for improved playability and performance.
Wide sole and beveled leading edge prevents digging into the turf.
Progressive offsets help square the face of the long irons at impact and allow easier alignment in the short irons.
Constant 4-degree loft spacing in the 5 through GW help to create consistent yardage gapping between the higher lofted, scoring irons in the set.
