The Mizuno MP-20 irons are a supreme set of muscleback irons that feature four separate models.
Mizuno’s headline MP-20 range of blades includes the MP-20 MB, which is the standard version, along with the MP-20 MMC, MP-20 HMB and MP-20 SEL (a dedicated left-hand design) to provide the most comprehensive of musclebacks yet.
Mizuno have focused on clean lines and eye catching designs that hark back to days of old in the last MB range, which replaces the very popular MP-18 irons range and now sits alongside the Mizuno JPX919 irons.
You’ll need to be a pretty decent player to get the most out of the blades and if you are a typical handicap golfer, stick with the cavity back models as they are much more forgiving when it comes to a bad shot or two.
What Mizuno say about the MP-20 iron range:
“We kept asking ourselves – why did players still talk about the feel of the older Mizuno blades – TN87, MP14, MP29, TP9?,” said Chris Voshall, Mizuno Golf Brand Manager.
“Despite our Grain Flow Forging process tightening up and an evolving CAD process that predicts vibration patterns – we were still missing something. The one element left from the old classics was a layer of Copper. After blind testing our players at the Valspar it was more than nostalgia – our test pool universally preferred the prototype with copper plating.”
Mizuno MP-20 MB Irons Review
The MP-18 are a classic looking muscleback, and carry that nostalgic look from deep into Mizuno’s history. They compact, but perform supremely well out of the middle of the blade.
The MP-20 MB irons are Grain Flow Forged HD from a single billet of 1025E Pure Select Mild Carbon Steel and layered with soft copper underneath the protective nickel chrome outer.
The top blade has been discreetly tapered for a eye-catching look, while the cambered sole has allowed a better spread of weight to make the irons more forgiving in off centre ball strikes.
The topline, meanwhile, is the thinnest that Mizuno have come up with in recent releases with the savings ranging from 0.05mm to 0.15mm throughout the irons compared to the MP-18s.
Mizuno MP-20 MMC Irons Review
The Multi-Material Construction (MMC) MP-20 irons have been refined in the second generation with a thinner topline and refined scoring irons introduced in the replacement for the MP-18 MMC.
The MMC is largely based on the MP-20 muscleback chassis, set flow and proportions, but they are designed to be much more playable.
That’s due the the presence of a titanium muscle plate and tungsten toe weight which help provide additional weight and move the centre of gravity to the sweet spot and become more forgiving. There is a second titanium muscle pad in the short irons from 8 iron to pitching wedge to create a narrower sole.

Mizuno MP-20 HMB Irons Review
The MP-20 HMB is the Hot Metal Blade and a full set of hybrid irons. Mizuno have taken the idea of making popular hybrids into a complete set and that is what the HMB offers, from long irons to pitching wedge.
The HMB irons stainless steel body and tungsten weighting construction (twin 12g weights in the 2-7 irons for stability and easy launch).
They feature Mizuno’s multi-thickness Grain Flow Forged Chromoly face and neck for ball speed in the 2-8 irons and a softer 1025E Pure select mild carbon steel for a soft and responsive irons in 9-iron and pitching wedge.
The irons are also layered with soft copper plating, like the other models in the range, and are finished with a nickel chrome outer for supreme feel.
Mizuno MP-20 SEL Irons Review
Mizuno have come up with trumps for the left-handers of the world by design a specific model with SEL known as the Special Edition Leftie.
They are based on the other right-handed models, but are an interesting blend of MP-20 MBs as mid to short irons and MP-20 HMB long irons.
