FEATURESForged with one-piece Grain Flow Forged HD Boron in Hiroshima, Japan where Mizuno irons have been produced since 1968. A Modified Teardrop flows through the set such that from stronger lofts with straighter lines to higher lofts with softer lines. A tapered design on the upper portion of the blade creates incremental vertical MOI for more consistent spin and more solid impact feel, particularly high impact. HydroFlow Micro Grooves are laser etched to release moisture and reduce spin drop off for increased wet weather performance. New Quad Cut + Grooves optimizing 6 groove geometry parameters deliver maximized spin for both full shots and partial shots in dry and wet conditions. 15 grooves on 46-54 degree wedges (full shots) and 17 grooves on 56-60 degree wedges (helps with partial shots). Grip: MCC Black/Grip.1025 Boron : A carbon steel that featurs 30% greater strength.
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.
