Mikawa Nagura 1165g

Mikawa Nagura are Tuff stones, a type of igneous rock formed from lithified volcanic ash. Mined in Aichi prefecture starting 700 years ago, they have been used in traditional Japanese sword polishing progressions. The mine has been closed since the 1970s.

We receive the stones from the wholesaler with rough chisel marks on both sides, and flatten them in our workshop. Although we have made a good effort to provide a flat surface for usage, we strongly recommend end users flatten the sharpening surface once more with a diamond plate.

 This particular stone is middle of the road in terms of hardness and friability. It can be slurried with a diamond plate for ease of use.
