The Petty is the perfect knife for slicing fresh herbs, cutting small vegetables and peeling fruits. Very versatile, this knife can even be used to debone poultry and small pieces of meat. Inspired by the French cuisine, the term ''petty'' is derived from the word ''petit'' and refers to a small chef's knife.
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.
