The best knife sharpener for Japanese knives works at a low angle, about 15° or less, and removes metal gently. Japanese blades are hard and thin, so aggressive carbide slots can chip them; water stones, ceramic wheels and 15° diamond sharpeners are safer.
We compared six sharpeners and stones on Amazon US by angle, abrasive and reviews.
