The Mizuno Men’s MP-67 Irons combine the tour winning characteristics of Mizuno’s classic blades with a Cut Muscle design, developed to fine tune feel and trajectory throughout the set. They feature the new 1025E Pure Select Mild Carbon Steel. Its softness and purity provide much better consistency which greatly improves distance control. This set of irons offers purer feel as a result and the distance control improvements have the significant effect of being able to outperform other blades.
