Naniwa Flattening Stone

Naniwa Flattening Stone is a specialized abrasive stone designed to level the working surface of whetstones. During the sharpening process, stones wear unevenly, which leads to the appearance of depressions and unevenness. This negatively affects the accuracy of sharpening and the uniformity of contact between the blade and the stone. Using a flattening stone allows you to restore the perfectly flat surface of the whetstone, ensuring stable and predictable results when sharpening and extending the life of the abrasive. Characteristics Purpose: leveling the working surface of whetstones. Size: 6-11/16" x 2-3/16" x 1-1/8" (170 × 55 × 30 mm). Abrasiveness: 220 grit. Material: abrasive composite. Conditions of use: use with water. Compatibility: most water and combination whetstones. Country of origin: Japan. How it works Flattening Stone has a coarse, flat abrasive surface that allows you to quickly remove excess material from protruding areas of the whetstone and renew its surface
