Knives stay sharp for a lifetime with Calphalon classic stainless steel Self-Sharpening cutlery with SharpIN™ technology. Sharpeners are built right into the 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 forged construction and a comfortably balanced handle. In addition, knife handles are labeled so you can always pull the correct knife out of the block. Gender: unisex.
