Welcome to Seisuke Knife!
Suehiro, a Japanese waterstone manufacturer from Niigita province in Japan, has a long history of producing high quality, yet affordable ‘toishi’ (sharpening stones). For many years now, they have produced an outstanding range of sharpening stones and continue to produce them today.
Quality is of utmost importance to Suehiro and that is made evident in his sharpening stones. A stone bought from them 30 years ago performs in the same way when used today. In Japan, you will likely see Suehiro sharpening stones almost everywhere; from department stores, home centers, and fine cutlery dealers.
Do not also soak in water finishing stones #3000 and above. After use, let the stone dry thoroughly. Returning a stone into its box while still wet or damp will result in molding and might decrease in quality. It usually takes 1 –2 weeks for us to restock should this item is not available.
