Features two tungsten carbide blades set at precise angles to ensure a perfect edge every time. With just three or four strokes through the carbide sharpening slots, you can restore the edge on even the dullest knives. Additionally, the two crossed ceramic rods, also angled for optimal results, provide a smooth, finished edge for already sharp knives. This sharpener is lightweight and portable, equipped with a lanyard hole for easy carrying, and has non-slip rubber feet for added safety.
