This Naniwa flattening stone keeps your whetstone level and in top condition for the best sharpening results. ---DETAILS--- Made in Japan, the Naniwa Whetstone Flattening Stone is designed to keep your whetstones in optimal condition for efficient sharpening. After frequent use, whetstone surfaces can dip and become concave – this flattening stone restores a whetstone's surface so it's flat again. Having a flat and level surface on whetstones is crucial for consistent sharpening. This levelling stone's coarse 220-grit rapidly cuts through worn material, while the deep diagonal grooves collect material removed to prevent clogging. How to Use: Soak the flattening stone in water for several minutes, as well as the whetstone you want to restore. (Skip soaking if using a no-soak whetstone.) Move the ridged side back and forth over the surface of the whetstone until the flat surface is restored. ---BENEFITS--- 'Over time, your whetstones wear down, but this Naniwa flattening stone brings them back to top condition.'
