An upgrade to the original Twinsharp, the Henckels Twinsharp Duo creates an edge quickly while finishing it with a polish that only ceramic can provide. The original Twinsharp combined both a sharpening carbide stage and a finishing ceramic stage into one slot, which meant that every time you tried to hone your knife, you were also removing steel because of the sharpening stage. With the Twinsharp Duo, your knives will last longer due to the sharpening and honing stages being separate. Need to sharpen that dull knife fast? Run it through the carbide stage first, then the ceramic stage. Need a quick hone to go through a tomato? Simply use the ceramic stage for a fine edge that will slice precisely. All this function is housed in a sleek stainless steel frame that is as elegant looking as it is useful.
