SUEHIRO Diamond flattening stone 150/500

Launched by Suehiro at the end of 2020, the brand new style of flattening stone is called Suehiro DADA. The genuinely functional holder, which doubles as a storage box, has two diamond discs of different roughness. The coarser one is #150, and the finer one is #500. It is also effective for flattening hard, rough ceramic stones. I just checked how DADA handles Haidu 250 and the Imanishi Arto 220. These two have provided a challenge lately. It worked well, but the most challenging for many has been the Kuromaku 120 stone leveling, and yes, DADA does well with this one. It looks like Naniwa's primary flattening stone has got a serious contender.
