A pre-polishing stone that has mud development. It feels harder when sharpening on it but the wide bevel polish does not translate to a level 4 stone. It could be used primarily for edge finishing and getting a toothy edge.

A ‘Higashi-mono’ (Eastern Mine Stone), Shoubudani is well known for producing a wide range of stones with different hardness and fineness. The Shoubudani mine produces some of the higher quality natural whetstones that are akin to Nakayama mine stones in their beautiful finish.
Meaning ‘pear-skin’, this aesthetic quality looks like tiny brown/pale dots on the stone. This quality can look similar to Su-holes on Suita stones as well as be a quality on Suita.
