Smith's Edge Grip Select 2-stage knife 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 Select has a non-slip base giving you added stability while sharpening your straight edge 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.
