A Diamond Steel will remove material from your knife. This will restore the V-shape of your blade edge to sharpen it. You would typically not use this method of sharpening frequently - only when your blade is feeling dull. If you use this method too often it will erode your blade very quickly. This is a great method for sharpening if you are a bit lazy or forgetful with knife maintenance (like me).
