The profile of the cutting edge is generally straighter and the tip is cut, similar to the kiritsuke, while the double bevel is characteristic of the gyuto. Kiritsuke Gyuto acts as a chef's knife in your kitchen and can do most of the tasks. It is usually found between 210 and 270 mm.
Simply explained, Aogami #2 developed by Hitachi Metals is a steel made from Shirogami #2 in which some chromium and tungsten are added for better durability and corrosion resistance. In addition to that, the higher carbon content of the steel allows for better cutting retention. Objectively, the Aogami #2 is an improvement over the Shirogami #2. For patina lovers, however, Shirogami steel will be more reactive to oxidation and could be an advantage.
