Discover our new whetstone that makes it easy to keep your knives truly sharp. With a double-sided surface, you can both repair and finely hone your blade quickly and efficiently. To make sharpening easier, the set includes an angle guide that holds your knife at the perfect 15-degree angle – ensuring precise and consistent sharpness. The non-slip silicone base keeps the stone firmly in place while sharpening. Soak the stone in water for just 5 minutes, then sharpen your knives in two simple steps to restore a razor-sharp edge. After use, the stone is easy to clean and dry, making it a practical tool for every kitchen.
