Mizuno MP-20 MB
Our take: Purists who want a blade designed for maximum shotmaking performance, distance control and a responsive feel, the MP-20 MB irons are among the crème de la crème. According to a tester, “The MP-20s are classic Mizuno irons, and the set checks all the look and feel boxes. And surprisingly, they weren’t as penal on off-center hits as I was expecting.”

Mizuno MP-20 MB Irons
The details: As expected, these irons are Grain Flow Forged from a single billet of 1025E mild carbon steel which lends the feel and performance competitive players have come to expect from Mizuno. The graduated taper blade is designed to promote a more penetrating ball flight as loft increases and the Tour-proven sole is both narrow and cambered for added versatility and shotmaking. A copper underlay makes these irons feel buttery soft at impact.
