This whetstone is a so-called semi-soaking tone. It works best after 5-10min of soaking. Do not store the stone in a basin of water. After sharpening, immediately wipe the stone clean with a towel. This will give the stone a clean look and start the drying process. Place the stone to dry in a position where it does not touch a solid surface. Place the stone on top of a pencil, for example. Allow the stone to dry slowly and quietly, without additional heating. Do not place the stone in direct sunlight. Do not allow the stone to freezing when wet. It takes more than 24 hours to dry. Store the stone protected from dents, e.g., in its box.
