Grain Flow Forged HD (High Density): The Mizuno MP-20 blade is forged from a single billet of 1025E mild carbon steel for unmistakable Mizuno feel.
Graduated Tapered Blade: Provides more penetrating ball flight (preferred by better players) as loft increases.
Copper Underlay: In a blind test nearly every Tour player chose the iron with a copper underlay which provides an incremental softer impact feel.
Tour-proven Sole: Many players requested a narrower, cambered sole during prototype testing as it provides better turf interaction from all lies.
Satin + Mirror combo finish: The MP-20 irons feature a sophisticated and straightforward aesthetic which reduces glare at address.
