Global Ceramic Water Sharpener

Adding water to the reservoir keeps the ceramic wheels lubricated and cool during use. This prevents the blade from overheating and helps flush away metal filings, resulting in a smoother, more consistent edge.

This sharpener is designed for standard kitchen cutlery. It is not suitable for serrated blades or single-bevel knives, such as traditional Japanese sashimi knives, which require specific sharpening angles.

The coarse white wheel is designed to repair dull or slightly chipped edges by removing a small amount of metal. The fine pink wheel is used afterward to polish and refine the edge for a razor-sharp finish.

After each use, simply rinse the unit under warm water to remove any metal residue from the wheels and reservoir. Allow it to air dry completely before storing it away.

Not at all. The manual design is straightforward and intuitive, guiding your blade at the correct angle through the wheels. It is a much simpler, safer alternative to using traditional loose whetstones.
