KitchenIQ's 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. Carbide blades and crossed ceramic rods feature pre-set sharpening angles that provide the proper sharpening angle every time. Carbide blades (Coarse) provide quick edge-setting capabilities, and the ceramic rods (Fine) are used for the final edge honing. These two stages offer the capability to put a razor-sharp edge on very dull or damaged blades and touch up already sharp blades. It comes with non-slip rubber feet and a soft grip rubber handle for comfort and steadiness when sharpening. The patented V-Grip™ bottom allows for added stability and comfort when using the sharpener on the edge of your countertop or table.
