Crafted by hand, these knives have a full tang and are made from tight grained, X50CrMoV15 German Steel for durability, stain resistance and exceptional edge retention. Each blade undergoes a six-stage heat treatment to maintain strength and function, and is hand sharpened to a 16-degree angle per side. The 4.75" handle and 5" blade are well balanced with HRC 58 +/- 2 on the Rockwell Hardness Scale. This set includes 4 steak knives. Cangshan's straight-edge blade is precisely tapered from base to tip, making these steak knives perfect for slicing all kinds of grilled meats. They are NSF International Certified and come with a lifetime warranty against manufacturer defects.
