Grain Flow Forged 4135 Chromoly: The Mizuno MP-20 HMB (Hot Metal Blade) irons deliver a soft, stable and consistent feel, with enough strength for high COR.
Dual Tungsten Weight (2-7 iron): A pair of 12g Tungsten weights located in the toe and heel for the hollow-bodied irons deliver lower/deeper COG and higher MOI.
Copper Underlay: In a blind test nearly every Tour player chose the iron with a copper underlay which provides an incremental softer impact feel.
Multi-Thickness CORTECH Face: Specifically designed for each iron the multi-thickness face is dialled in to be consistently hot across the entire surface.
Full Satin Brush Finish: The MP-20 HMB irons feature a sophisticated and straightforward aesthetic which reduces glare at address.
