Due to its hardness, it can also be used for back-honing. About 30 years have passed since the stones from the east and west were exhausted. It is difficult to obtain high-quality whetstones. Even whetstone shops in Kyoto do not have good whetstones in stock. Okudo Suita is of good quality. There are also Namito (ordinary whetstones), but Okudo Suita is better. Nowadays, there are good artificial whetstones, but natural whetstones are still fun and interesting to sharpen with. Thank you.
