Keep your knives razor sharp with this two-stage sharpener designed specifically for the narrower-blade geometry of Asian-style knives. Use the coarse, carbide-steel slot to set a new edge (for extremely dull knives) and the fine, ceramic slot to polish and finish the edge. To use, simply place the sharpener on a secure surface, grasp the handle, and pull the knife through the desired coarse or fine slot. A few pulls are all that's necessary to achieve a sharp edge. FEATURESCoarse and fine blades allow you to establish a new edge or refresh an edge that just needs a little polish. V-shaped slots for easy sharpening. Rubberized base helps prevent slipping, and the loop handle provides a secure grip while sharpening. Manufacturer: Wüsthof . Material: Plastic, ceramic, carbide. Care: Hand wash only.
