SEOUL, South Korea, December 10, 2025 /PRNewswire/ — Adak Golf, a rapidly growing golf brand from South Korea, is expanding rapidly into the US and Japanese markets. It offers industrial-grade technology to everyday golfers seeking high performance and durability in their golf equipment.
For a long time, golfers looking to restore the spin performance of their wedges had limited and often risky options. Traditional golf club groove maintenance tools like files or metal cutters could damage the clubface or injure the user. The brand “Adak Golf,” developed by the innovative South Korean manufacturing company Nextzhen Co., Ltd., is setting a new standard in this field with the launch of the world’s first diamond-infused golf club groove sharpener and cleaning tool.
Unlike traditional golf accessories, the Adak Groove Sharpener is a golf club maintenance tool born from advanced manufacturing technology. The product was designed and manufactured by Nextzhen Co., Ltd. (CEO Jung Hun Hwang), a company internationally recognized for providing high-precision glass substrate polishing technology for displays to world-leading tech firms, including Samsung’s mobile division.
At the core of Adak’s innovation is a proprietary elastomer infused with micro-diamonds. This groundbreaking abrasive allows for a safer and more controlled method to clean and polish the grooves on a golf club’s striking face without cutting into them, thereby restoring the performance of wedges and irons.
Key benefits include:
• Club Restoration: Even damaged irons, worn out or rusted, can regain near-new performance.
• Enhanced Backspin Control: Sharp, debris-free grooves are essential for precision in approach shots, enabling wedges to generate more stopping power. This performance benefit has been independently verified through rigorous testing using a swing robot by the Korea Institute of Golf & Sports (KIGOS).
• Built-in Safety: The flexible, non-metallic design minimizes the risk of damaging the clubface or injuring the user’s hand, a significant improvement over hard metal groove sharpeners.
Adak’s product gained significant attention after being featured on GOLFWRX, one of the most influential golf communities in the United States. In a July 2025 article titled “Korean Gadget Report: How Adak’s Diamonds Are Redefining Your Wedge Game,” GOLFWRX detailed the tool’s unique technology and measurable performance gains. The article generated substantial interest among avid golfers, proving Adak to be a game-changer in the industry.
Building on its successful online track record, Adak Golf plans to expand into US retail stores and golf shops in 2026. In addition to its flagship groove sharpener, the company is developing a range of innovative products, including performance-enhancing accessories like a swing tempo training glove. New products are being developed based on the consistent philosophy of applying industrial-grade technology to modern golf equipment.
The Adak Groove Sharpener and Cleaner are available for purchase with expedited shipping on Amazon in the United States and Japan.
