The Japanese word Gyuto (牛刀) literally translates to beef sword. The gyuto is the equivalent of the Western chef's knife, and is designed to cut everything: vegetables, meats and fishes. It is made to be used with the push-cut method, lifting the blade between each cutting motion, or with the rocking motion method. It is important that the blade is straight upon impact with the cutting board to avoid damage to the knife edge.
Aogami literally translates to "blue steel", so "super blue steel" is the translation for Aogami Super. Manufactured by Hitachi Metals Ltd, this carbon steel grade has one of the highest hardness levels and is one of the most renowned in Japan. In addition to containing more carbon, chromium and tungsten than Aogami #1, it also contains molybdenum. The high carbon content allows for greater hardness, but on the other hand, reduces the corrosion resistance and makes the steel more brittle. Chromium and molybdenum counterbalance the effect of the high carbon content by improving corrosion resistance. Tungsten greatly increases the wear resistance of the steel, making it less brittle. The combination of all these characteristics makes Aogami Super a practically superior carbon steel compared to other steels in this category.
