About the Mizuno MP-37
The MP-37 is a Grain Flow Forged players iron sold alongside the MP-32 and MP-33, covering the 2-iron through pitching wedge. It shares the loft ladder of the MP-30 before it, with a 35-degree 7-iron and a 47-degree pitching wedge, but cuts offset to a flat 0.11 inches through the long and mid irons. Bounce is comparatively high for a blade, starting at 4 degrees in the 2-iron and reaching 7 degrees at the wedge. Lengths and lofts listed are the standard men's steel-shaft specification.

Finding a used set
The Mizuno MP-37 ran from 2004 to 2006 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
