Known outside Japan better under the Bester brand, Imanishi has produced high-quality whetstones in Kyoto. I have picked out the most sought-after and best-known Imanishi stones for sale.
The Bester series 220, 400, and 1200 are the most well-known and highest quality soaking stones, and the 4000, 6000, and 8000, respectively, have gained a reputation as Splash-and-Go stones and especially for sharpening carbon steel. In addition, stones like Arashiyama and Kitayama have a reputation for being high quality and one of the easiest whetstones to use on this grit level.
