The ONOFF KURO is a players cavity iron from a Japanese brand most golfers outside Japan have never held. ONOFF, built by Globeride, sits in the premium tier where forged feel and craftsmanship matter more than a bargain price. The KURO name means black, and the 2025 model carries the compact, clean look that better players tend to want at address.
The number that tells you the most here is the 7-iron loft: 34 degrees. That is traditional, not jacked. While a lot of modern irons strengthen lofts to fake more distance, the KURO keeps its 7-iron where a 7-iron has always lived. You get honest gapping, a steeper landing angle, and the spin to hold greens instead of a lower, running ball that skips off firm surfaces.
This is a cavity back, so there is help built into it, but it is aimed at players who make consistent contact. The set runs from a 4-iron at 24 degrees down through a 50-degree wedge, which means you can build a tight gapping ladder into your short irons without a separate specialty wedge for the top end.
In short
The ONOFF KURO (2025) is a players cavity that adds forgiveness without much extra size. The set runs 4-iron to 50-iron with a 34° 7-iron. It carries a $1,199 MSRP.

The cavity back construction moves weight to the perimeter of the head, which widens the sweet spot and steadies mishits without turning the KURO into a shovel. The head stays compact, the topline is on the thinner side, and offset is kept modest so the club sits down cleanly behind the ball. That combination reads as a players iron, not a game improvement one. Lofts stay traditional across the set. The 4-iron is 24 degrees, the 7-iron 34, and the wedges come in at 46, 50, and beyond. Four-degree gaps hold through most of the set, so your distance windows stay even from long iron to short iron. The 46 and 50 built into the set give you gap wedge coverage without hunting for a matching finish.
The ONOFF KURO's 7-iron is lofted at 34° - traditional - aligned with classic iron loft standards. For a golfer with an 85-95 mph swing speed, this projects to a 7-iron carry of approximately 136-146 yards. The 5-iron (27°) to 7-iron gap of 7° is well-gapped, which may create overlapping distance windows with similarly lofted fairway woods or hybrids.
It is a players cavity, which sits between the two. You get perimeter weighting and a forgiving cavity back, but in a compact head with a thin topline and modest offset. It rewards decent contact rather than covering for it the way a full game improvement iron does.
34 degrees, which is traditional. Many modern irons strengthen the 7-iron to 28 to 30 degrees to add distance, but the KURO keeps it at 34. You lose a bit of raw yardage compared to those clubs and gain a higher, softer landing that holds greens.
The set runs down to a 50-degree wedge, with a 46-degree gap wedge in between. That gives you short scoring coverage without buying a separate specialty wedge to match the finish, though most players still add a sand and lob wedge below the 50.
ONOFF is a premium Japanese brand focused on forged feel and finish rather than mass-market pricing. If you want soft feedback, clean looks, and something most of your playing partners have never seen, it is worth a look. If you want the widest fitting network and easy resale, the bigger brands are simpler.
Probably a little, and that is by design. With a 34-degree 7-iron versus a 30-degree one, the KURO launches higher and lands steeper. You trade a few yards for better stopping power on approach shots and more consistent gaps between clubs.
