This Lansky sharpener is the Quick Fix - a combination of two great sharpening technologies - tungsten carbide and ceramic rods - a quick and easy way to keep your knives sharp out in the field or on the job. Just 3-4 strokes across the tungsten carbide heads will put a new, sharp edge on your knife. A few strokes over the crock sticks will touch up or polish a blade
