Are you ready to salvage your dull knives? Or just bring your less-than-perfect blades into brand-new condition? Save your money by using our sharpener to put your old kitchen tools into perfect cutting condition. The Zulay knife sharpener is guaranteed to do the job. Whether your knife is almost beyond salvage or it just needs some touch-up sharpening, you have the correct tool for the job with our 2 stage sharpening system, a state of the art mechanism to repair any knife. Our non-slip base and ergonomic handle makes sharpening easier and safer than with competitor's models, even electrical power sharpners, and stone. Keep yourself and family safe by using only sharp knives. Dull knives are a health risk because if they cut into your skin, it gives you jagged cuts that take longer to heal and are more prone to infection. Although this is counter-intuitive, it is nonetheless true. INSTRUCTIONS: 1. Place the knife sharpener on a flat surface. 2. With one hand hold the knife sharpener by the stainless steel rod. 3. For a very dull knife, hold the knife by the handle and pull it along the coarse slot toward you 2 to 4 times. 4. Move the knife to the fine slot and pull it toward you 2 to 7 times or until sharpness as desired. This is to polish the blade off and to hone the knife.
