UNDERCUT CAVITY TECHNOLOGY
The QL iron is manufactured using a state-of-the-art casting method to produce our patented undercut cavity from one piece of 431 stainless steel. This new casting method allows the mold to have a retractable core, producing a clean, consistent one-piece cavity that offers remarkable feel. The deep-channeled undercut cavity allows the CG to be moved lower and further back from the face for outstanding forgiveness and distance.

THIN FACE, LOW PROFILE TECHNOLOGY
The QL's super-thin face (2.3 millimeters) and the heavy perimeter weighting of the head design move more than 40% of the head's total weight to the outer edges of the club. This extreme perimeter weighting and low profile design make the club more stable at impact - keeping you on target, even on off-center hits.
