About the Mizuno JPX-921 Forged
The JPX-921 Forged is a one-piece Grain Flow Forged Chromoly 4120 iron with a face thinned to 2.6 mm and a redesigned sole and topline compared with the JPX-919 Forged. It was sold as a 4-iron through gap wedge set with a players' cavity profile and offset running from 0.150 inches down to 0.091 inches. Lofts were strengthened by one degree through most of the set relative to the JPX-919 Forged, giving a 31-degree 7-iron and a 45-degree pitching wedge, which is still two degrees weaker than the JPX-921 Hot Metal. Lofts, lies and lengths listed are the men's standard steel-shaft build.

Finding a used set
The Mizuno JPX-921 Forged 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.

- mizunogolf.com JPX921 Forged club-specification page (4-7 iron loft/lie/offset/length, matching the above)
- Swing weight is omitted because published tables give it as a regular/stiff pair (D1/D3 in the irons, D2/D4 in the wedges) rather than a single value. The gap wedge length is listed as 35.25 inches by 2nd Swing and 35.5 inches by TGW; 35.25 inches is used here to match the rest of the JPX series.
