Victorinox Honing Steel Black Plastic Handle ComboCut

 A steel doesn’t sharpen your kitchen knives. Honing a knife, as it's called, is not the same as sharpening a knife, what you are basically doing is re-aligning the knife blade similar to what a barber does with a straight razor. A knife looses its edge a bit while cutting, a steel repoints the blade. Yes you still will need to sharpen your knives from time to time.
