This Diamond-electroplated sharpener ensures an efficient, fast and sharp result. For use in all areas of home and business. Excellent for hunters, butchers, chefs, fisherman, and for the home kitchen. This steel will sharpen all types and sizes of knives from pocket knives to professional forged knives. The oval profile makes for an easy and more accurate finish and the handle design is both aesthetic and practical. With regular use, any knife’s edge will lose its “bite”. Using a diamond grit sharpening steel will realign the edge and keep it sharp for continued cooking enjoyment. You should always use a honing steel that is longer than your largest knife.
