Now in a beautiful silver finish, the Ai-ONE #1 CH is a traditional heel-and-toe weighted blade design with rounded bumpers and a crank hosel, giving this putter significant toe hang that makes it best suited for golfers with more face rotation and arc in their stroke. Powered by Callaway's industry-leading Artificial Intelligence engineering, the Ai-ONE insert delivers remarkably consistent ball speeds across the entire face — so even off-center putts roll the distance you intend. Paired with the new SL 90 Stroke Lab steel shaft and a sleek blasted silver finish, this is a putter that combines Tour-proven technology with timeless, premium aesthetics. Includes an original Odyssey headcover.

Technology in Detail
Ai-ONE Insert — AI-Engineered Consistency
All golfers — even the best Tour players in the world — miss the center of the face from time to time. When you lose ball speed relative to a center hit, the ball does not roll as far as you intended, causing missed putts or leaving the ball well short of the hole. Odyssey's answer is the Ai-ONE insert: designed using Callaway's industry-leading Artificial Intelligence and super-computing capabilities to create the most advanced insert in golf. The aluminum backer features unique AI-engineered contours that are co-molded directly to a White Hot urethane striking surface. These contours actively work to maintain consistent ball speed across the entire face — whether you strike it on the sweet spot or towards the heel or toe — so you get reliable distance control on every putt. The result is a putter that effectively gives you a larger, more forgiving sweet spot without compromising the soft, precise feel that White Hot urethane has always been famous for.
Panlite Window — Showcasing the Science
The Odyssey Ai-ONE Silver features a distinctive Panlite window — a panel made from a unique automotive-grade polymer — built into the back of the putter head. This transparent window allows you to see straight through to the intricate contoured topology of the insert's rear surface, making the AI engineering visible rather than hidden. Beyond the visual drama, the Panlite construction contributes to the multi-material design that optimizes the overall weight distribution of the head, complementing the performance characteristics of the AI-designed insert. It is a bold design statement that underscores the technology story of the Ai-ONE line.
Crank Hosel & One CH Head Shape
The One CH combines a tried-and-tested #1 blade shape — featuring a traditional heel-and-toe weighted construction with rounded bumpers — with a crank hosel neck. The crank hosel is specifically engineered to position the shaft well forward of the face, creating a full-shaft offset that is clearly visible at address and helps golfers place their hands ahead of the ball. Most importantly, this hosel geometry produces a significant 45° of toe hang, making the One CH an ideal match for players who putt with a noticeable arc and natural face rotation through impact. The rounded bumpers contribute to a clean, classic look that has been trusted by golfers for decades.
SL 90 Stroke Lab Steel Shaft & Removable Weights
The new SL 90 Stroke Lab steel shaft is a lightweight steel shaft with 20–30 grams of counterbalance weight engineered into the butt end, depending on the grip selected. This counterbalancing is an evolution of Odyssey's proven Stroke Lab weighting philosophy, designed to lighten the perceived weight of the grip end while adding mass to the head end of the equation — encouraging a smoother, more consistent pendulum tempo that appeals to a wider range of golfers than previous Stroke Lab designs. Complementing the shaft are removable sole weights available in 5, 10, 15, and 20-gram options. These allow you to easily customize the total head weight to match your preferred feel, stroke speed, and the pace of the greens you play most often.
Premium Blasted Silver Finish
Odyssey has taken its most popular Ai-ONE models and made them available in a beautiful new silver finish that is both classic and premium. The blasted silver treatment replaces the original navy blue PVD colorway — chosen to broaden the Ai-ONE's appeal to golfers who prefer a more traditional, understated aesthetic at address. The silver finish pairs naturally with the champagne-toned details of the insert area, giving the putter head a rich and refined visual character. Far from a simple color swap, the silver versions represent a considered response to golfer feedback and bring the Ai-ONE platform to a new audience of players who want cutting-edge performance in a timeless-looking package.
White Hot Urethane — Tour-Proven Feel
White Hot urethane has been one of the most celebrated face materials in putting for decades, trusted by Tour professionals and amateurs alike for its distinctive soft, responsive feel and the precise feedback it delivers at impact. In the Ai-ONE Silver, this iconic urethane striking surface is co-molded directly onto the AI-contoured aluminum backer, ensuring that the feel characteristics of White Hot are preserved even as the underlying structure works to equalize ball speed across the face. The combination means you do not have to sacrifice feel for forgiveness — the Ai-ONE Silver delivers both simultaneously, giving you the confidence to commit fully to every putt.
