Easy to use, fast cutting, slightly hard but buttery feeling Aiiwatani stone which makes a fine and bright kasumi finish with good contrast, can be graded higher if used with a drying used slurry with light pressure. Makes a great edge, highly recommended for making a fine finished edge with some bite.

Aiiwatani: A ‘Higashi-Mono’ (Eastern Mine) whetstone that is close in proximity to Takashima and Wakasa, two mines known for their high density stones. Aiiwatani are great shiage-toishi(fine stones) when you are looking for a refined edge. Typically more mellow in cutting action, but this can lead to a cleaner polish.

Asagi: 

This aesthetic term refers to the general color of the stone. Typically, Asagi stones are grey, light blue, greyish-blue/green, and tan. They are usually quite clean stones that are on the harder side. However, softer Asagi stones are great for knife polishing.

Nashiji:

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.
