20° Grinding Angle
The manual knife sharpener features a high-quality plastic housing and a rubberized handle. The strong, ultra-sharp, and durable 2-phase edge has a grinding angle of 20° and is convexly ground. It is particularly well-suited for all smooth and serrated household, leisure, and commercial knives.
