Jason Day’s Innovative Equipment Change: 3D-Printed Prototype Irons
At the close of the previous year, PGA Tour star Jason Day made waves in the golf equipment realm by introducing a cutting-edge addition to his golfing arsenal: 3D-printed prototype irons from Avoda featuring progressive face curvature. This innovative design aims to minimize side spin on off-center hits, effectively counteracting the gear effect and enhancing precision.
In a recent appearance on Skratch’s "One Hole With," Day elaborated on these unique custom Avoda irons. He explained how the 2026 models were specifically engineered to complement his distinct shaft lean, optimizing both performance and control.
The Technology Behind the Irons
During his conversation with Dan Rapaport, Day emphasized the technology that sets his new irons apart:
“Essentially the technology behind it, it’s a gradual progression of curved face, so it actually matches my forward press down onto the ball. A lot of clubs these days are built at a certain sole angle. It’s a one-size-fits-all approach, which doesn’t suit everyone.”
A Custom Fit for Performance
Day is candid about how his playing style impacts his club selection. He remarked that he cannot utilize Scottie Scheffler’s TaylorMade P7TW irons due to their design, saying:
“If I tried Scottie Scheffler’s TWs, right? Beautiful looking club. I dig them. But I can’t play them because he gets so far laterally left that if he was narrower, he’d hit it right. He has to get it so far out that way…. Whereas I like to put a lot of lean on the shaft.”
He further explained how the sole angle of his new irons is custom-designed to accommodate his unique swing mechanics:
“When you look at my sole, it’s at a different angle and it’s actually custom designed for my lean.”
