About This

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
Quad Cut Grooves: Milled narrow/deep grooves optimized for stronger lofts and wide/shallow grooves optimized for higher lofts
Hydroflow Micro Grooves: Laser etched microscopic grooves help channel away moisture for maximum spin in wet conditions
Face Milling Lines : Increased surface roughness to increase spin nearer the green.
