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
