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 pre-set 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.
