Jason Day adds mysterious Avoda prototype irons in Utah | Tour Report

Welcome to GOLF’s Fully Equipped’s weekly Tour equipment report. Each Friday of PGA Tour weeks (plus other times, if news warrants), GOLF equipment editor Jack Hirsh will run you through some of the biggest news surrounding golf clubs on Tour, including changes, tweaks and launches.

Some golfers think they might need 15 clubs, but Jason Day only has 13 in the bag this week at the Bank of Utah Championship.

But playing a $6 million PGA Tour event with one less tool in the bag than everyone else is not the biggest story about the former World No. 1’s gear this week.

That honor would fall to his new set of Avoda protype irons.

You may recall the Avoda name from last year, when Bryson DeChambeau had the company build him a set of 3D-printed irons which got approved for play just days before the 2024 Masters. DeChambeau went on to win the U.S. Open with those irons, which featured a unique bulge-and-roll design to help mitigate side spin on mishits, similar to woods.

Day’s prototypes are 5-AW combo set of muscle backs and shallow cavity backs and also feature what the company calls a “curved face” design. Instead of going with a single-length set like DeChambeau, Day’s irons are standard length.

In his first round since the BMW Championship in August, he opened with a three-under 68 on Thursday at Black Desert Resort. After the round, Day explained what led to this point; he said he felt like his iron game wasn’t where it needed to be, so he started looking at options with coach Collin Swatton. Day hasn’t ranked inside the top 100 in strokes gained: approach on the PGA Tour since 2016, when he was the No. 1 Player in the World.

“I’m a free agent there so I can go out and see what the best of the best is,” Day, who was most recently playing a set of TaylorMade P7CBs. “Stumbled across Avoda in a way that like obviously Bryson had some success with it. He won with the Avoda irons at the U.S. Open at Pinehurst. But I just told my coach, just have a chat to the guys, see what they think.

“[Swatton] got off the phone and called me and he goes, ‘Man, in all the years I’ve been doing this, I’ve never come across the guys the way they explained everything.’”

PGA Tour Live host Lisa Cornwell reported on Thursday’s broadcast that Swatton’s conversation with Avoda’s Tom Bailey and Tom Lewis lasted 90 minutes. That led to Day going out to meet the Avoda team in person and they 3D-printed multiple prototype sets of irons to his specifications.

Day still lost shots on approach in his first rounds with the new irons, but he led on that he doesn’t believe this is his final setup.

“There is a process there. After this week we’re obviously going to get back together and see what needs to kind of be improved,” Day said. I think currently right now I would like to see a little bit— a tiny bit more offset. Try and get a little bit more turn. If that has a little bit more offset it will actually elevate the ball a little bit more in the air, which would be nice.”

He also added that he wants to look at the grooves to see if he can get more spin.

The 37-year-old Day also made two other changes to his iron setup with longevity in mind. He’s long been a user of the True Temper Dynamic Gold X7 shaft, the heaviest and stoutest shaft in the Dynamic Gold lineup. This week, he’s gone to a 110-gram KBS TGI 110X graphite shaft in his irons and two Vokey wedges. He also added JumboMax JMX Zen Lite grips, which together with the lighter shafts have made it “easier on the body.”

The TGI shafts also match the KBS Proto shafts he put in his woods for bend profile.

“The theory I think I have the same profile shaft from 60-degree all the way up to driver,” he said. The goal is to be able to swing, just pretty much have one swing like whatever ball flight you want, whether that’s a draw or a fade. For me it’s a draw. To go up there and hit a draw and pretty much put the same swing on it and hopefully it produces the same shot over and over again.”

Finding the 14th club

With the new iron set, Day has joined a growing number of players on Tour who are dropping 4-irons completely from their bags, which brings us back to the lede of this story.

Day hasn’t yet found a replacement for the 4-iron slot in his bag, which was previously a TaylorMade P790.

He did become the latest player to add Callaway’s new 2025 Apex Utility Wood to his setup, adding a 21-degree head bent to 18.6˚ to serve the slot after his 6-year-old TaylorMade M6 3-wood. The next club is his 5-iron.

Callaway 2025 Apex Custom Utility Wood

The Apex UW is designed for serious, avid golfers seeking the perfect blend of a fairway wood’s power and a hybrid’s versatility. Engineered with Tour feedback and loaded with performance technologies, it delivers a higher, more neutral ball flight with the control all players demand. 
TUNGSTEN SPEED WAVE
A dynamic, 41g+ tungsten wave structure positions mass low and forward, enhancing ball speed and launch—particularly on low-face strikes where players tend to lose distance.
STEP SOLE DESIGN
A redesigned sole with a stepped geometry reduces turf interaction, helping to maintain swing speed through impact and promoting more consistent contact across different lies.
TRIAXIAL CARBON CROWN
The lightweight carbon construction allows for strategic weight redistribution, creating a more forgiving clubhead while refining launch and spin for greater shot-making control.
TOUR-INSPIRED SHAPING
Designed with input from the world’s best, the compact, refined shape and neutral face angle inspire confidence at address and deliver workability from tee to turf.

“I’m actually playing 13 clubs here this week. I’m missing a club,” Day said. “I would like to play a 23-degree [UW], and that would fit perfectly between the 21-degree and the 5-iron that I’m playing. It goes about 230, 229. The 21-degree Apex, Callaway, that goes about 250 in the air, so i need something right smack between it and that should cover the whole thing.”

Day seems to be doing all sorts of testing this week… not just on the range, but during the actual tournament and he said he’s still got more to work on coming up.

“I think we’re in the testing phase,” he said. “You know, we still got to get the gappings right, have to get the spins right, so obviously that is going to be more testing coming up for me.”

With Day’s spot in Signature Events next season locked up, he can be pretty free in any of the fall events he chooses to play. It’s almost like he’s using this week as a testing ground of sorts for his new gear setup.

It will be interesting if other pros who finished in the FedEx Cup top 50 also utilize this strategy moving forward, the rest of this season or next year.

Can Cobra’s 3D Printing completely change the irons market? – You can see custom Cobra Golf 3D printed irons on the PGA Tour, but how soon might we see these custom options available to the consumer?

Cobra 3DP Tour Custom Irons

The KING 3D Printed TOUR irons utilize 3D printing technology to unlock a new realm of performance. Their one of a kind design features the most forgiving blade shape on the market, delivering the forgiveness that aspirational players need, and the sleek looks and soft feel that better players desire.
3D PRINTED STEEL CONSTRUCTION
Each iron is fully 3D printed from 316 stainless steel. 3D printing provides significant advantages over traditional methods of casting and forging, unlocking more design freedom and significant performance improvements.
FORGIVING PLAYERS BLADE SHAPE
3D printing has unlocked new design possibilities, enabling COBRA engineers to create a compact blade shape with the mass properties (high MOI, low CG) of a game improvement iron without sacrificing looks and soft feel that better players demand.
INTERNAL LATTICE STRUCTURE
COBRA took a muscle-back blade shape (similar in size and shape to the KING TOUR iron), and transformed the inside of the blade into a complex internal lattice structure to reduce the weight of the club by 33%. That discretionary weight was repositioned to optimize feel, CG position, and MOI.

This trendy putter design is popular in junior ranks, too (INSIDERS ONLY) – I just came back from Pennsylvania’s PIAA State High School Championships and I saw dozens of low torque putters. Has the real onset boom only just begun?

L.A.B. Golf OZ.1i HS Putter

It’s heel-shafted. It’s still L.A.B. Heel-shafted putters have been around forever. No reason they shouldn’t be balanced. OZ.1i HS is the first heel-shafted putter with Lie Angle Balance, giving golfers the traditional look so many love with the ease of use that defines L.A.B.
This isn’t just an OZ.1 i with a different neck. Lie Angle Balance demands precision, so we re-engineered the OZ.1 i chassis for a no-compromise heel-shafted design. Our proprietary aluminum riser connects the shaft to the head in a way that maintains Lie Angle Balance and delivers the same forgiveness as the OZ.1i.
Golfers who prefer a heel-shafted look no longer have to compromise on performance. And because it’s a L.A.B., you can count on every putter being individually built and balanced. With OZ.1i HS, it’s not where the shaft goes. It’s where the ball goes.
