This classic-looking spinoff series was created in response to tour requests. The Ai-ONE putter, which has been gaining popularity among pros and amateurs alike, now features a different spinoff series, the Ai-ONE SILVER. The difference is the color: instead of navy, the stainless steel body is clad in a beautiful, traditional silver. Many tour players favor this classic look, and this model fulfills their desires. Of course, the face features the Ai-ONE insert, which minimizes ball speed loss on mishits. It also features a polycarbonate window that allows you to see the complex ridges created by AI on the underside. Approximately 15g weights are located at the toe and heel of the sole. The lineup includes four models: the blade-type #1 CH and DOUBLE WIDE DB, and the popular horn-shaped #7 DB and #7 S. All are equipped with steel STROKE LAB 90 shafts. Each putter is available in 33-inch and 34-inch lengths. [Features & Benefits] ■ Silver replaces navy. The Ai-ONE SILVER Putter is a model featuring a brighter silver finish on the stainless steel body of the Ai-ONE putter. Many tour players prefer the classic silver color, and this model was created to meet their demand. ■ Two blade and two horn-shaped models are available. The Ai-ONE SILVER Putter lineup includes four models: the standard blade "#1 CH," the wide blade "DOUBLE WIDE DB," the popular horn-shaped "#7 DB" with a double-bent neck, and the "#7 S" with a short slant neck. All models feature approximately 15g of sole weights in the toe and heel. The aluminum sole plates of the three models except the "#1 CH" also feature the navy color of the Ai-ONE putter. ■ AI-designed inserts minimize ball speed loss. Like the Ai-ONE putter, the Ai-ONE SILVER putter features an Ai-ONE insert, a complex AI-designed aluminum part with raised ridges layered on the underside of the resin part on the impact side. While a 1cm deviation in the impact point on the toe or heel typically reduces ball speed by approximately 20% (2m shorter on a 10m putt), the raised aluminum part reduces the reduction in ball speed to approximately 5% (50cm shorter on a 10m putt). The resin face also features grooves, which are designed to mimic the feel and sound of a White Hot insert, achieving a similar feel. A window is also provided to reveal the shape of the underside of the face. As with the Ai-ONE putter, the Ai-ONE SILVER putter incorporates a technology never before seen in clubs or putters, allowing players to enjoy the unique technology. A transparent polycarbonate window is located on the back face of the #1 CH and DOUBLEWIDE DB putters, and on the front sole of the #7 DB and #7 S putters. Through this window, the intricate AI-designed ridges on the back of the insert can be seen. ■Stroke Lab 90 shaft, made entirely of steel. Like the Ai-ONE putter, this putter features the STROKE LAB 90 shaft. Despite being made entirely of steel, it achieves a lightweight weight of around 90 grams, with a thicker butt section. By reducing torque, it suppresses unnecessary shaft movement during the stroke. A counterweight is also installed inside the shaft near the grip. Combined with the lightweight shaft, this increases the moment of inertia of the entire putter, providing players with a consistent and stable stroke.
