Knives stay sharp for a lifetime with the Calphalon Classic Self-Sharpening 15-pc. Cutlery Set featuring SharpIN™ Technology. Sharpeners are built right into the knife block, automatically sharpening straight edge knives every time you remove them from the block to ensure peak sharpness at the start of every cutting task. Knives are made from high-carbon, no-stain forged steel, and feature full tang construction and a comfortably balanced, triple-riveted handle. In addition, knife handles are labeled so you can always pull the correct knife out of the block. The Calphalon Knife Set includes an expanded selection of large and small knives for dicing, chopping, paring and more, plus eight steak knives.
