Whetstone Amakusa Whetstone Red Torato Natural Whetstone Type 15 ・Type 15 Approximately 21.5 x 7 x 6 cm, Approximately 2330g #Compare with Amakusa Treasure Island's Amakusa Whetstone. This belongs to the category of medium to coarse grit. Suitable for rust removal, agricultural tools such as sickles, etc. You can use any surface for sharpening. As it is a natural product, there may be hard spots, soft spots, air bubbles, spots, and slight chips. Air bubbles are preferred because they collect the grinding slurry. Occasionally, it may crack. We cannot provide support for this. Please purchase only if you understand that it is a natural product. The clearer the wood grain, the higher the possibility of cracking from the darker areas. [Reference Explanation] Amakusa Whetstone is produced from the island of Oyano-machi, Kamiamakusa City, Kumamoto Prefecture, a place associated with Amakusa Shiro's war funds. It has long been favored for sharpening kitchen knives, carpentry tools, and agricultural tools. Recently, due to the spread of artificial whetstones and the aging of producers, they have become less available in the market. This time, we will deliver them directly from the local Amakusa to those who can use them. *The grit size varies for each natural whetstone. ◎Torato (Red) Reference grit size: Approximately 500-800 ◎Nakajiro (Special Prepared Water) Intermediate between red and white ◎Johaku (White) Reference grit size: Approximately 1000 *Currently, there is no excavation of Johaku.
