Smiths 2-Step Knife Sharpener features two tungsten carbide blades with pre-set angles to ensure the perfect edge every time. Three or four strokes through the carbide sharpening slots will restore the edge of a very dull knife. The two crossed ceramic rods also have pre-set angles and provide a smooth finished edge to already sharp knives. This portable sharpener is lightweight and features a lanyard hole, non-slip rubber feet for added safety, and even floats in water. It can be used on all types of knives, especially fillet knives and it is perfect for all your hunting, fishing, and outdoor adventures.
