The EdgeWare Ceramic Edge Electric Knife and Scissors Sharpener uses interlocking ceramic wheels for fast and precise sharpening of both sides of a knife blade at the same time. The electric knife sharpener produces a superior edge while removing minimal material from a knife edge. Compared to diamond, or synthetic abrasives, a ceramic knife sharpener produces a smoother and sharper edge. The electric knife sharpening feature can be used for even light touch ups of an already sharp knife. One manual slot offers carbide blades to use for setting the initial edge on a knife to match the sharpening angle of the ceramic wheels. The other manual slot consists of triangular shaped ceramic stones that are designed to follow the shape of a serrated knife and ensure consistent sharpening. The stones can also be used to polish a freshly ground edge on straight knives. Includes a retractable scissors sharpener. The EdgeWare Ceramic Edge Electric Knife Sharpener will sharpen straight edge knives, serrated knives, and both left- or right-hand scissors.
