Safe and easy to use, this two-stage knife sharpener requires nothing but a few easy strokes to keep blades sharp. Its V-shaped cutting head with two crossed carbide blades puts a quick edge on knives. Simply place the gadget on a flat work surface and hold the E-Z grip handle with one hand and the knife handle with the other. Insert the knife blade fully into the slot at a 90-degree angle to the sharpener and pull back a few times to sharpen. After setting the knife"s edge with the carbide side, use the unit"s ceramic side to nicely finish the edge. The two-stage knife sharpener measures 9 by 3 by 1-1/2-inches.
