A hook is a hand tool used for securing and moving loads. It consists of a round wooden handle with a strong metal hook about 20 cm long projecting at a right angle from the center of the handle. The appliance is held in a closed fist with the hook projecting between two fingers. This type of hook is used in many different industries, and has many different names. It may be called a box hook, cargo hook, loading hook, docker's hook when used by longshoremen, and a baling hook, bale hook, or hay hook in the agricultural industry. Other variants exist, such as in forestry, for moving logs, and a type with a long shaft, used by city workers to remove manhole covers. Smaller hooks may also be used in food processing and transport.
