Editor’s Conclusion
Nothing feels like a Mizuno. That’s the slogan that comes with each new set of Mizuno irons, a bold claim of quality, precision, and feel. The JPX 921 range boasts four new sets - the Tour, the Forged, the Hot Metal, and the Hot Metal Pro - to bring that famous Mizuno feeling onto the fairways of your local club, whatever your ability as a golfer.

Let’s start with the set aimed at elite golfers, the JPX 921 Tour. These had big shoes to fill, with the previous model being used by Brooks Koepka as he romped to four major championships in a little over two years, despite not being on Mizuno’s sponsorships books - he just loved the clubs so much he chose to put them in the bag. That’s a big statement, and the 921 Tour’s back it up.

Key Features

Despite being aimed at better players, they’re not scary to look down on like some blades, with a slightly more forgiving top line and a longer face. This, according to Mizuno, means the irons will work better for players who like to hit the ball straight than those who play with a lot of shape; think Luke Donald rather than Bubba Watson.

This straight ball flight is backed up by ‘stability frame’, which is supposed to help with a consistent, straight ball flight. It has to be said, these are gorgeous looking blades: classic without being boring, sleek without being scary, and all the reviews show that they back it up in feel. These are irons aimed at good players - single figure handicaps and below - so they will jar your hands on off centre strikes, and have very little offset to protect against a mistimed swing.

But with that being said, they’ll offer a bit more protection than some other ‘tour’ level clubs, so if you’re a low handicapper who’s been nervous to try ‘truer’ blades but wants that professional precision, these could be a good compromise. Equally, however, if you’re an elite level golfer (scratch or better) and shot-shaping and workability are big deals for you, it might be worth looking at the MP-20 blades instead.

The next set in the lineup is the JPX 921 Forged. These are - probably obviously, due to the name - forged irons designed to offer a little more forgiveness than the Tour model, but while still keeping that trademark Mizuno feel and precision. Interestingly, these use Mizuno’s Chromoly steel, a low alloy material that they had previously employed in their game improvement irons, with the idea of creating a more powerful club. They certainly look it - visually, the Forged set is very similar to the Tour set, except ever so slightly chunkier and more forgiving.

But don’t get me wrong - this is still a sleek and refined-looking club. The Forged irons will be naturally longer than their Tour counterparts, both due to the additional weight in them but also because of the lofts.

Comparisons

To compare, the 921 Tour seven iron has thirty-three degrees of loft, while the 921 Forged only has thirty-one. This is a recent trend in iron sets - as technology improves, manufacturers can crank down the loft while still maintaining super high ball flight, allowing you to hit the ball that extra bit further. These irons aren’t power machines, however.

They are much closer to the Forged than the Tour sets in terms of looks and feel. If you want the full Mizuno experience but need a bit more help with ball striking, and are in the low to mid handicap range (8-20), these are a cracking set of clubs that are well worth considering.

The Verdict

Finally, this brings us to the Hot Metal and Hot Metal Pro models. These irons aren’t forged, which means they don’t quite have the feel of Mizuno’s other two offerings - rather than being soft, they are a bit firmer.

For higher handicapped golfers, however, this is a worthwhile trade-off for the many benefits the Hot Metal sub-series brings. Cavity-backed for extreme forgiveness and high launch, they are perfect for golfers who struggle for confidence in their irons. No matter
