How to identify this generation
- A Mizuno Pro script sits above a shallow cavity with the running-bird logo near the toe, and S-4 on the hosel.
What to notice in the specifications
- Mizuno’s S-1, S-3 and S-4 tables list the same lofts, lies and lengths for every club they share (S-1 starts at 4-iron); read the hosel marking to tell the heads apart.
Read our loft guide for a worked example of comparing the numbers, and our used iron checklist before relying on a seller's description.
