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.
Shirogami #1 by Hitachi steel co translates to white steel #1 and is an improved version of Shirogami #2 as it contains a higher carbon content. It is named after the color of the paper in which it is packaged once produced. It is considered one of the purest steels, after Tamahagane, which allows for a sharper edge than most other steels. However, it will generally be more brittle and can break more easily due to misuse. Mastering the forging of shirogami #1 to exploit its full potential is not simple and requires an expertise that few blacksmiths have. It is in the process of making a Mizu Honyaki type knife that you will find the shirogami #1 in its most difficult to forge version, but also the sharpest.
