The Mizuno Pro Irons are the result of a longstanding connection between Mizuno's club engineers and the legendary Grain Flow Forging plant in Hiroshima, Japan. This unique relationship has enabled the creation of increasingly intricate designs flawlessly incorporated into the finished equipment. Every fraction of a millimeter and subtle curve has been meticulously considered, shaping the future of golf club technology.

David Llewellyn explained, "The Mizuno Pro 243 is the model that’s advanced the most, mainly due to evolution on the manufacturing side. It’s one thing for the R&D team to design a thinner face iron with stronger materials in the CAD world – but something else to have it Grain Flow Forged to those specifications and strength requirements."

Chris Voshall noted, "The Mizuno Pro 243 looks much more compact than its predecessor, even though the performance has stepped up. The long and mid irons are flying far enough that we’ve had to modernize the lofts in the scoring irons. Mizuno Pro isn’t stuck in tradition – we’re led by performance above what might be expected historically.”
