- Hot Metal has a listed SW at 54°; the Pro row on the same page stops at GW.
- Mizuno lists both hands in satin chrome across 4–SW.
What the chart cannot tell you
A loft figure alone does not predict carry distance or determine a suitable fit. Head design, shaft, strike, swing speed and delivery also matter. Check actual loft and lie with a qualified fitter when a used set's history is uncertain.
