Smith’s 2-step knife sharpener features two tungsten carbide cutting heads with pre-set angles to ensure the perfect edge every time. Three or four strokes through the carbide cutting heads will restore the edge on a very dull knife. The two fine ceramic rods also have pre-set angles and provide a smooth finished edge to already sharp knives. It is lightweight, portable, comes with a lanyard hole, and has non-slip rubber feet for added safety. Excellent for use on all types of knives, especially fillet knives.
