Sharpening instruction

1. Soak the stone in the water for 5 minutes, and then put it on a steady platform. Sharpening the knives with one or two steps is decided by the degree of blunt tool.

Generally we advise you to use it once a week or daily use, and always keep your blade sharp

2. Please wipe it with wet cloth or rinse it with water after sharpening the tool, and then dry it. Clean the stone surface with a soft brush and put it in the air to make it dry.
