Grain flow forged in Hiroshima, Japan, Mizuno has refined the art of feel for over 50 years. The MP-20 brings that feel to the new line. Balancing 1025E pure select mild carbon steel and a soft copper plating with nickel-chrome, Mizuno believes these irons deliver an impact sensation recognized as their purest ever.
Three distinctive irons — MP-20 (Muscle Back), MP-20 HMB (Hot Metal Blade) and MP-20 MMC (Multi-Metal Construction) — each offer their own unique appeal. You can opt for a full set of any model or blend them to create your own custom set.
MP-20 is the ultimate Mizuno muscle back, heavily influenced by the most iconic blades from Mizuno’s past. Forged from a single billet of 1025E mild carbon steel, it is subsequently layered with soft copper plating beneath a protective nickel chrome for superb feel and feedback.
MP-20 MMC is the second generation of Mizuno’s multi-material concept. It offers a thinner topline and refined scoring irons. The club's proportions are engineered to be more playable through the use of a titanium muscle plate and tungsten sole weight.
MP-20 HMB incorporates a full set of performance hybrid irons which, according to the company, delivers a sharp “Tour ready” profile. Inspired by the proliferation of long iron replacements on Tour, the MP-20 HMB extends the concept right through to the wedge.
“Most modern muscle backs and limited ‘Tour edition’ irons can be traced back to the great Mizuno blades. Though what makes a Mizuno iron truly exceptional is everything you can’t see,” said David Llewellyn, R&D Director, Mizuno Golf. “If you could peel back the chrome plating, you would find a sandwich of nickel and soft copper before the Grain Flow Forged HD chassis. Under a microscope, you can see a perfect flow of grain within the steel from the hosel to toe, compacted tighter in the hitting area. Designers can mimic our lines, but not what’s inside.”
