About the Mizuno MP-9
The MP-9 was one of the first irons in Mizuno's Mizuno Pro MP line for the North American market, a Grain Flow Forged blade that ran from 1988 to 1994 and helped establish the MP name among tour players - Sandy Lyle famously played Mizuno blades of this family when he won the 1988 Masters. Japanese catalogues list it as sharing its specification with the domestic MS-9. Lofts are classic, with a 35-degree 7-iron and 47-degree pitching wedge, and the lie angles are flat by modern standards. The 1- and 2-iron lofts are documented but their lie and length were not published in the surviving table, so those fields are omitted.

Finding a used set
The Mizuno MP-9 ran from 1988 to 1994 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.
- KEN's Mizuno Pro lineage catalogue notes (ameblo.jp/inuken-2019, 'ミズノプロの系譜（２）仕様データ1980年代版'): the MIZUNO PRO MS-9 table, annotated as 'same as the USA model MP-9 around 1990', gives lofts for 1-SW and lie/length for 3-SW; lengths are the Japanese-market steel spec
- Production window 1988-1994 and popularity: swingyard.com and golfspan.com Mizuno-irons-by-year histories both date the MP-9 from 1988; golfspan credits Sandy Lyle's 1988 Masters win to the model's family
- This is a single primary spec source with the twin-model caveat, so confidence is low; offset, bounce and swing weight were never published and are omitted. The PS club is Mizuno's pitching-sand wedge between PW and SW
