Mikawa Nagura 2015g

 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 one is a very light cream colour all the way with minimal orange streaks and black dots. The light colour is desirable and the wholesale cost of the stone was increased as a result. This stone is hard and not as friable as other examples. Consider soaking the stone before use, or using a diamond plate to slurry the stone. However, the performance of the stone for burnishing details is superior without slurry.
