Wüsthof 4347 – Kitchen knife sharpener with ceramic and carbide sharpening section.

Safe and easy to use, this two-stage knife sharpener requires nothing more than a few simple pulls to sharpen the blades. Can also be used for serrated edge blades (only the ceramic part needs to be pulled). Soft-touch handle.

2-stage knife sharpening:
Place the sharpener on a flat work surface. Hold the sharpener in one hand and the knife in the other. Insert the knife blade fully into the slot with the sharpener at a 90° angle. Apply moderate downward pressure on the blade while pulling the knife towards you in the appropriate groove. Repeat this process, always pulling the blade from the handle to the tip (never back and forth) in the carbide or ceramic slot.
The first grade carbide (coarse) sharpens a dull edge. The second grade ceramic (fine) provides a polished, razor-sharp edge. A fairly sharp knife only requires this light work.
Always clean the sharpener after use. Clean with a damp cloth or soft brush, wipe dry. Do not rinse with water.
