A ‘Higashi-Mono’ (Eastern Mine) whetstone that is close in proximity to Takashima and Wakasa, two mines known for their high density stones.

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.
This aesthetic quality looks like tiny black dots, or little sesame seeds in the stone. This quality typically translates to having a fast cutting speed.
