Yaginoshima Asagi lv 2-4 (a1209)

That one is super cool Yaginoshima that is very hard to rate 

They are fast, very fast but not soft at all 

you can actually get all the way to lv 4 with them if you work on mud as they are quite hard stones that is amazingly fast 

they can be used on knives and razors and tools 

even so it say start from lv 2 they have to be treated as very hard stones 

so they can be used with naguras as well 

super clean stone no lines or inclusions 

super cool and bit weird stones that is very cheap
