Each knife is precision forged from a single piece of sturdy high-carbon steel that resists stains and corrosion. Wüsthof's Precision Edge Technology (PEtec) ensures a 20% sharper blade with twice the edge retention. Full tangs are triple riveted to handles for exceptional durability and control. Each knife has a recessed bolster that facilitates honing and sharpening the entire length of the cutting edge; a heel bolster provides added balance. Sleek contoured handles are made of smooth polypropylene.
