The difference is instantly noticeable with TaylorMade RocketBladez Irons. Speed Pockets in the 4-7 irons optimize face flexing, feel and performance at impact. The ultra-thin face design combines with Inverted Cone Technology to enable maximum playability and distance. Strategically redistributed weight located in the sole of each iron simplifies launch, heightens peak trajectory and allows for a steep, quick-stopping descent angle.
