Iron set. Hot Metal Blade irons that have evolved the flight and ease of use while maintaining a muscle-back-like head shape. The 4-8 irons are precision forged from high-strength chrome molybdenum steel (SCM420). The 9, PW, and GW are precision forged from mild steel (S25CM). The flight of chrome-moly and the feel of forging are coexisting in one set. You can experience the flight of Hot Metal Blade chrome-moly and the good feel of soft iron. Mizuno's unique Core-Tech Face is adopted. By making the center lower part (near the hitting area) thinner than the previous "Mizuno Pro 225" irons, the repulsive force is improved. Achieved the highest repulsion in Mizuno forged iron history. Tungsten, about 1.6 times that of the previous "Mizuno Pro 225" irons, is placed in the lowest possible position (4-7 irons). The center of gravity is designed to be low and the depth of the center of gravity is deep, and the sole's thin part is expanded to increase the high-speed area. It has a tungsten structure for ease of use and flight. Mizuno's commitment to feel is designed with the latest technology. The height, size, and tone of the sound that affect the feel are tuned in units of several tens of hertz. This unique design method of Mizuno creates a comfortable feel unique to Mizuno. NS Pro Shaft The ZELOS series, which brings distance performance to steel shafts with unprecedented lightness and large bending, making stability its weapon. As the second installment, it has been newly released with increased weight compared to ZELOS7. The large bending width of the tip-weighted shaft enables flight that rivals carbon shafts, and the excellent operability and well-regarded comfortable feel due to weight reduction satisfy the pride of steel fans. It is a specification that allows more active, athlete-oriented senior players, female professionals, and competitive female amateurs to attack the pins more aggressively. ■ Flex: R ■ Kick point: Tip Zelos 8 Flex R 6 pieces from 5 to P We recommend replacing the grips.
