These fine-edge steak knives cut meat effortlessly, leaving it perfectly tender. Each Professional S SIGMAFORGE blade is precision-forged from a single piece of high-carbon, special formula stainless steel. The FRIODUR blades are ice-hardened for extra corrosion resistance and cutting edge retention. The hand-polished, laser-controlled edges ensure ultimate sharpness. Full tangs provide balance and durability. All this combined with the ergonomic ABS, 3-riveted handles results in effortless cutting. Professional S knives are dishwasher safe, but hand washing is recommended.
