1731 was designed for Zwilling J.A. Henckels by Milan-based designer and architect Matteo Thun. His design focuses on both form and function. The sigmaforged blade features a exclusive high-performance steel called Cronidur 30. This steel is used in the aerospace technology because of the hardness of the steel and is highly corrosion resistant - Rockwell hardness of 60. The blade undergoes an extra step called Friodur- ice hardened. This process enhances the quality of the steel. The unique wedge-shaped blade delivers optimum stability with a full cutting edge. To add to the knifes character, you will enjoy the warm comfortable handle made of untreated oiled ebony wood. 1731 is a true masterpiece.
