The thin face (half the thickness of the S55 iron) yields greater ball speeds for increased distance throughout the set with higher overall trajectories and precise control. A hydropearl chrome finish repels water for more control and helps minimize fliers from wet conditions and lies in the rough.
The unprecedented feel is achieved through a combination of soft 431 stainless steel and a larger surface area behind the face that houses an elastomer insert. The insert is "activated" at impact, resulting in more vibration damping in your hands for a softer feel and pleasing sound.
Nearly "pure" tungsten toe weights (netting a 70% increase in mass relative to the S55 iron) are pressed into the toe of every head to increase MOI, a key factor in the precision of the iBlade iron.
Refined bounce angles and ample heel relief, optimized with the same sole width as the S55 iron, produce a workable sole design for confident shot making from all conditions. Further precision comes from the milled tour-spec grooves and precision-machined fly-cut face.
