Crafted by hand, these knives are made from X50CrMoV15 German Steel, known for its durability, stain resistance, and exceptional edge retention. The blades undergo an extensive six-stage heat treatment process to maintain their strength and functionality. They are then hand-sharpened to a 16-degree angle on each side. With a well-balanced 4.75" handle and a 7" blade, these knives have a Rockwell Hardness Scale rating of HRC 58 +/- 2. This vegetable Cleaver, also known as a Nakiri, is versatile for push cuts, slicing, dicing, mincing, and cutting fruit or cheese. These knives are NSF International Certified and come with a lifetime warranty against manufacturer defects. To maintain their quality, wash the knives with warm water and a small amount of detergent, rinse carefully, and dry with a towel.
