Suehiro is a well-known Japanese manufacturer of whetstones. I have recently expanded Suehiro's offerings for the simple reason that customer feedback has been great.
The Cerax range includes the CR series with a stand. The 401 and 1010 models without stand have a reputation for really high-quality stones, and I also had to include these two so-called name stones, Ouka and Rika. The top of the range of sinking stones.
In addition to these, the new Debado range, which is aimed at professionals and active hobbyists and requires little water in use, was also included. Debado is slightly harder and therefore more durable than the Cerax range.
