The EdgeWare Edge Grip 2-Stage Knife Sharpener is lightweight, portable, and easy to use on either a flat surface or the edge of your countertop or table. Coarse carbide blades provide quick edge setting. Fine ceramic rods provide final edge honing. These two stages offer the capability to put a razor sharp edge on very dull or damaged blade and touch up already sharp blades. Pre-set sharpening angles ensure the proper sharpening angle and guaranteed results every time you sharpen your knife. Non-slip rubber feet and a soft grip rubber handle provides comfort and steadiness when sharpening. The patented V-Grip bottom allows for added stability when using the knife sharpener on the edge of a countertop or table.
