Grain Flow Forged HD: One-piece Grain Flow Forged HD from 1025E Pure Select mile carbon steel at Mizuno's iconic facility in Hiroshima, Japan. Where Mizuno irons have been produced since 1968.

Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback

Copper Underlay: Thin copper layer beneath a nickel chrome to provide a further enhanced impact feel

Grain Flow Forged Chromoly: Our strongest Forged material with the solid, soft consistent feel of Grain Flow Forged

Micro Slot Technology: Milling the head from the sole up creates a Micro-slot that activates the strength of the 1025 Boron material for added distance and increased forgiveness

4120 Chromoly with Flow Microslot: Featured in the 4-7 irons, a wider, longer micro-slot to create a more expansive high energy area in each club face. Resulting in a higher flight and faster ball speeds.

1025E Pure Select Mild Carbon Steel 8-GW: Solid feel and control where most wanted, with modern lofts to maintain even distance gapping through the set.

Wrap-Around Sole Grind: Heavy relief around the sole for improved turf interaction and seamless transition from micro-slot 7 iron into traditional 8 iron construction.

Compact Player's Profile: Dramatically reduced topline and blade length throughout the set.

Increased Bounce: Another direct request from the tour. Increased by a degree in the long irons and 2 degrees in the scoring irons for improved turf interaction.

Satin Nickel Chrome Finish : An elegant, yet durable, non-glare finish.
