From the Narutaki mine a huge professional size hachimai strata tool stone.

This dense stone is perfect for chisels and plane blades, it will cut any steel and will begin to remove a Atoma #600 diamond plate scratch pattern within 30 passes with just clear water. Not slurry necessary.

Although green, that color overwhelms the hints of yellow streaking, a bit like a kiita in disguise and in fact there are 2 kiita colored namazu lines at one end.

The back is hand chiseled and although one corner at on end is fore shortened the stone seats well in a stone holder. The stones missing corner is reflected in the price.
