King F9 One Length 5-PW, GW Iron Set with Steel Shafts

Product Overview: The KING F9 SPEEDBACK ONE Length irons are engineered to simplify your game by reducing variables in your swing to increase accuracy and consistency. Features: SPEEDBACK DESIGN. Much like a wide-body kit adds to the stability of a racecar, SPEEDBACK shaping utilizes a belt of steel that adds mass low and wide, creating a lower, deeper CG that maximizes ball speed, launch and carry while maintaining a conventional sole width. BEST IN CLASS FEEL . A 3-piece multi-material medallion combines aluminum, TPU (Thermoplastic Polyurethane) and acrylic foam. These lightweight materials damp vibrations to promote a softer, more responsive feel that is not normally found in a game improvement iron. CNC MILLED  FACE AND GROOVES. CNC milling is a highly precise manufacturing method that is typically only found in forged player's irons. This process allows us to create perfectly flat faces, and precise lofts and groove shapes in every iron we manufacture. PROGRESSIVE SPIN TECHNOLOGY. Progressive groove shapes are CNC milled into each face to optimize spin performance in the long irons, mid-irons and wedges. PROGRESSIVE HOSEL LENGTHS. Shorter hosels in the long irons (4-6) lower the CG to increase launch and distance, medium hosels in the mid irons (7-9 iron) create a gradual transition from the long irons and taller hosels in the wedges (GW-SW) raise the CG to promote control and accuracy.
