Smith's Diamond Edge Grip Max 2-Stage Knife and Scissor Sharpener is made with both carbide blades, perfect for bringing your dull and damaged knives back to life, and ceramic blades for those quick touch-ups and polishing of already sharpened knives. The Edge Grip Max has a non-slip base giving you added stability while sharpening your knives and Smith's patented Edge Grip technology allows for sharpening on a table or countertop edge to prevent your larger knives from dragging over the surface. This Edge Grip sharpener can be used to sharpen straight and serrated knives, as well as your favorite pair of scissors.
