Improvements in performance only made possible through the long-term relationship between Mizuno's R&D team and its exclusive Grain Flow Forging plant in Hiroshima, Japan.
At Mizuno's exclusive facility where Mizuno irons have been produced since 1968. A wider, longer micro-slot to create a more expansive high energy area of clubface – resulting in a higher flight and faster ball speeds. A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the sensational feel of Mizuno's Grain Flow Forged heads.
Solid feel and control where most needed, with modern lofts to maintain even distance gapping through the set. Applied to closely match the vibration patterns identified with a soft muscle-back feel. Heavy relief around the sole for improved turf interaction and seamless transition from micro slot 7 iron into traditional 8 iron construction.
Dramatically reduced topline and blade length throughout the set. Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction. A less reflective, modern finish.
