The ultimate Mizuno muscle back – heavily influenced by the most revered blades of Mizuno’s past. Grain Flow Forged HD from a single billet of 1025E Pure Select Mild Carbon Steel – then layered with soft Copper plating beneath a protective Nickel Chrome for legendary feel and feedback. Grain Flow Forged HD in Hiroshima Japan, from 1025E Pure Select mild carbon steel, then plated in soft copper and Nickel Chrome – the original layering from Mizuno’s great TN87 blade. Honed by studying elements of Mizuno’s most played/retained tour iron models – by both contracted and non-contracted tour players. Usage amongst ‘free-agents’ on tour provided a new perspective. A discreetly tapered top blade and cambered sole allow a fuller vertical spread of weight to forgive strikes high or low from the face – without distorting the traditional muscle back appearance. Mizuno’s thinnest topline of recent generations – a response to feedback from our tour players. The MP-20 #3 iron is reduced by 0.05m and pitching wedge by 0.15mm (compared to MP-18). Combination of chrome finishing to eliminate areas of high glare in the playing position.
You will get: The Grain Flow Forged material has a sturdy, velvety, consistent feel and is our strongest Forged material. Higher purity with a tolerance that is six times tighter than the industry norm. A thin copper coating is placed behind a nickel chrome layer to further improve the impact sensation.
