"UST シャフト mamiya 2017 Recoil 400 Series Iron Shaft"

"Recoil technology allows the golfer to load and unload better on partial and full shots for improved distance and trajectory control. The Recoil shaft also increases the spring effect in the walls of the shaft for efficient energy transferred to the ball for increased velocity and greater distance. The unique composite construction creates a higher damping rate equating to better feel and less stress on joints in the hands, wrists and elbows."
