Produced in Japan by a traditional 3rd generation whetstone manufacturer. When we first visited their facory we were happily pleased to see just how handmade these stones were. Each batch is hand mixed, pressed, and fired in a kiln for 36 hours. Every batch is quality tested for cutting performance and optimum hardness. The best qualities of these stones are the exeptional cutting speed and feedback during use.
Tanso stones are soaking stones and should be placed in water for about 10 minutes before use. Like all soaking stones, when dried they should be in a cool and dark area to avoid drying the stone too rapidly. Drying your stones in a hot area or in direct sunlight can cause damage over time.
