Dual Stone, Grit 300

A new development, which will primarily appeal to sculptors, is the new Dual Stone series from Suehiro. The extremely hard abrasive grains have a relatively hard, non-porous bond. The main advantage of this series is that you can sharpen with water or oil, whichever you prefer, so the series can be optimally complemented with Arkansas stones. You should rub the stones with water or oil before use and store them in a dry place. Because of the non-porous bond, the grits must be rated much finer.
