Simple and dependable, the V-Slot™ Knife and Scissors Sharpener is quick, safe, and easy to use. It only takes three or four strokes to put a sharp edge on any straight-edge household knife. The “V” shaped sharpening slot incorporates two crossed carbide blades, which are preset at the correct sharpening angle. The scissors sharpener uses a patented “FLOATING” ceramic rod that adjusts to fit the precise bevel of the blades. The soft grip handle provides a firm comfortable hold when using this simple, but effective sharpener on household knives or scissors.
