You can use it for both shaping and finishing. By sharpening with a calm mind, even beginners can reproduce a professional sharpness. Comes with a non-slip base, so you can use it right away when you want to! ◾︎How to use◾︎ 1. Soak the whetstone in water for about 15 minutes. 2. While applying water, sharpen with the coarse grit, then the fine grit, as if stroking. The key is to fix the angle and sharpen calmly without straining. 3. Dry and store after use. Storing it with the rubber base can prevent damage to the corners of the whetstone and the storage location. The angle guide is attached by inserting it into the knife. When the knife is laid down, the guide touches the whetstone first, maintaining a constant angle. I have also used it, and it's a highly recommended item because it's very easy to maintain the angle. ◾︎Product Details◾︎ Contents: Double-sided whetstone x1, Rubber base x1, Angle guide Material: White corundum (whetstone) Size: Whetstone 180mm x 60mm x approx. 30mm Rubber base 183mm x 64mm Weight: 700g per whetstone
