Excellent for establishing kasumi polish. An awesome stone to look at while you work, and the finish on the steel is consistent. A thick stone that will last for years with proper care.

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.
