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.
1025 Boron : A carbon steel that featurs 30% greater strength.
Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback
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.
Loft/COG Flow Design : The COG of these wedges flows throughout the set to give more control and versatility.
Bounce Specific Sole Grinds: Matched bounce and sole grind for an ideal level of versatility.S-Type:  high bounce with limited relief for full shots.D-Type:  mid bounce with moderate relief for gentle manipulation.C-Type:  mid/high bounce with generous relief for a wide range of players and conditions.V-Type:  high bounce with aggressive relief for versatility on square and open faced shots.X-Type:  low bounce with aggressive relief for advanced players for the most versatility.
Loft Specific Head Shapes : Graduated head shapes from pitching wedge to lob wedge ideally suited for how each wedge is used.
Copper Underlay: Thin copper layer beneath a nickel chrome to provide a further enhanced impact feel
Refined Topline: Mass taken from the toe portion and a lower hosel blend creates a smaller profile without loss of effective hitting area.
Quad Cut + Grooves: An adjustment of the groove shoulder camber and the taper of the groove profile allows a tighter groove pattern for increased spin rates on all shots.
Wrap-Around Sole Relief: Increased sole relief from heel to toe across all 5 grind options.
Spin-weighted Blade Design: A flared upper portion of the blade creates higher spin and penetrating trajectory, particularly from strikes high on the club face.
