NOTE!

"Splash-and-Go" stones do not tolerate prolonged storage in water. Use water only as much as the stone requires. Do not submerge the stones in a water basin. After sharpening, immediately wipe the stone clean with a towel. This keeps the stone looking tidy and initiates the drying process. Place the stone where it does not touch a solid surface. Let the stone dry horizontally, for example, by placing it over a pen. Allow the stone to dry slowly and peacefully without additional heating. Do not expose the stone directly to sunlight, and do not let the stone freeze while damp. The drying process takes more than a day. Store the stone protected from impacts, for example, in its box without the possible original foam padding. Please do not put the stone in a plastic bag while still damp.
