Yoshihiro INOX Aus-10 Stain-Resistant Steel Ice Hardened Petty Utility Knife (4.7'' (120mm)) INOX Aus-10 is commonly used in high-end Japanese knives and provides a good foundation to build a knife with well-rounded attributes. While very similar to AUS-8, the increased carbon content in AUS-10 Stainless Steel results in a knife with higher edge retention and durability. The quality of the steel together with its expert craftsmanship makes this a professional quality chefs knife with an excellent blend of razor sharpness, durability, and comfort that is unrivaled in its price range. Sometimes called a utility knife, the Petty is a smaller version of a chefs knife but is bigger than a Paring knife. The Petty fits in small places that require more dexterity than bigger chefs knives while handling bigger jobs than a Paring knife can take care of. The Petty will soon become the go-to knife in your kitchen. The difference will be felt right away when a hand-forged Japanese Petty knife of incomparable sharpness is used for smaller precision tasks such as peeling, trimming, and slicing small fruits and vegetables to handling bigger tasks as a small chefs knife. A razor sharp Petty knife can intricately carve and style vegetables and fruits for beautiful presentations and garnishes, performing just as well for bigger jobs such as preparing meals. Proudly made in Japan. This knife is complimented with a premium Western Style Handle that extends to the full tang of the knife and ergonomically welds to the hand for seamless use.
