Nobody Could Copy Mizuno Forged Irons. Here’s Why That’s a Myth

In 1999, 1,215 sets of Mizuno irons were in play across the professional tours, which put Mizuno number one in total iron count, according to Golf Business News. Yet Mizuno also once fell from number one to number four on tour within a single season, according to MyGolfSpy. So why were its forged irons so difficult to reproduce? This video follows Mizuno from a baseball shop in Osaka in 1906 to a forging plant in Hiroshima. It tests the idea that nobody could ever copy a Mizuno forged iron and shows what the evidence supports instead: a manufacturing system built around consistency, a partnership with the forging company Chuo that goes back to 1968, and a Grain Flow Forging process patented in 1998.

Mizuno's own records disagree on whether it was forged or cast. 1968: Mizuno begins producing iron heads with Chuo in Hiroshima. 1987: Nick Faldo receives Mizuno heads at Greensboro the week before the Masters and wins the Open Championship later that year. 1998: Grain Flow Forging is patented. 1994-1999: players with Mizuno irons win 37 tournaments and more than $73 million in prize money. What the sources do not show: there is no public record of a boardroom decision to keep forging, so the video does not invent one.
