A utility knife is any of various types of knives used for general or utility purposes. The utility knife was originally a fixed blade knife with a cutting edge suitable for general work such as cutting hides and cordage, scraping hides, butchering animals, cleaning fish, and other tasks. Craft knives are tools mostly used for crafts. Today, the term "utility knife" also includes small folding or retractable-and-replaceable-razor-blade knives suited for use in the general workplace or in the construction industry. The latter type is sometimes generically called a Stanley knife, after a prominent brand.
