Taking care of your Wusthof knives is important. Dull knives can easily be sharpened by using abrasive utensils like the Wusthof 10-inch sharpening steel. The grooved, magnetic steel rod attracts loose metal fibers during sharpening for easily restoring the cutting edge of a knife and can actually reshape and restore the blade edge to its original angle and sharpness. The slip-resistant handle allows you to get a good grip and the hook allows you to hang the steel while not in use.
