The Mizuno JPX923 Forged Iron Sets (Steel Shaft) are a mid-sized, full body Grain Flow Forged iron delivering a perfect balance of ball speed, stability, and feel. Using Mizuno’s 3rd generation of Chromoly Forging (4-7 iron) incorporates a milling slot that extends wider to heel and toe. The irons showcase a thinner top line throughout, plus compact scoring irons (8-GW) and bevelled sole for improved turf interaction.
Features & Benefits:

Noticeably shorter blade length and more compact from 7 iron to GW – for precision where most needed. - WHITE-SATIN BRUSH
Non reflective, Chrome plated finish to reduce bright light glare. - FORGED IN HIROSHIMA JAPAN
One-piece Grain Flow Forged HD from 1025E Pure Select mild carbon steel at Mizuno’s iconic facility in Hiroshima, Japan – where Mizuno irons have been produced since 1968.
