About the Mizuno MP-20 MB
The MP-20 MB is Mizuno's muscle-back blade for 2019-2020, Grain Flow Forged HD from a single billet of 1025E Pure Select mild carbon steel and finished with a soft copper underlay beneath nickel chrome plating. It uses a flow-tapered blade profile, so the long irons sit slightly lower in centre of gravity than the scoring irons, and offset is minimal throughout at 0.087 inches in the 7-iron. Lofts are traditional rather than strengthened, with a 34-degree 7-iron and a 46-degree pitching wedge, and the stock set runs 3-PW. All figures are the men's standard steel-shaft specification.

Finding a used set
The Mizuno MP-20 MB ran from 2019 to 2021 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
