The perfect tool for keeping the edges sharp on all of your Victorinox cutlery! The Swiss Classic 10" honing steel is long enough to sharpen most any knife in your block from a small chef's knife to large butchering knife. Unlike a knife "sharpener", a honing steel is used by professionals after each each use to roll the edge back to it's original position and keep it at the ideal angle for maximum sharpness. With routine use, you should only have to "sharpen" your knives once or twice a year.
