The Qi irons from TaylorMade are built for maximum distance forgiveness and consistency. The patented face design allows for optimal face flexibility to reduce cuts, keeping the ball flying straight and far down the fairway. Each iron head is individually designed to give players the performance they need, with an emphasis on maximum distance and forgiveness. The Center of Gravity is placed lowest in the long irons and moves progressively higher in the short irons to produce better launch and playability in the long irons while promoting control and precision in the short irons. To improve consistency, Qi irons feature a larger sweet spot and increased blade length with a redefined leading edge. This TaylorMade golf club set is available in stiff flex and features steel shafts. It's designed for male golfers.
