The Shinkansen knife sharpener is angled to exactly match the recommendations for sharpening Japanese knives. Fill the chamber with water. It cleans the stones and prevents the metal from heating up. Pull the knife blade vertically back and forth through the white stone 7-8 times. Repeat in the pink stone, then wash the knife by hand. The grinder can be used for all kinds of knives with smooth blades.
