A hook is a tool consisting of a length of material that contains a portion that is curved or indented, so that this portion can be used to hold another object. In a number of uses, one end of the hook is pointed, so that this end can pierce another material, which is then held by the curved or indented portion. ==Variations== * Bagging hook, a large sickle or reaping hook used for harvesting grain * Bondage hook, used in sexual bondage play * Cabin hook, a hooked bar that engages into an eye screw, used on doors * Cargo hook (helicopter), different types of hook systems for helicopters * Crochet hook, used for crocheting thread or yarn * Drapery hook, for hanging drapery * Fish hook, used to catch fish * Flesh-hook, used in cooking meat * Grappling hook, a hook attached to a rope, designed to be thrown and snagged on a target * Hook (hand tool), also known as longshoreman's hook and bale hook, a tool used for securing and moving loads * Hook-and-eye closure, a clothing fastener * Hook and loop fastener * Lifting hook, for grabbing and lifting loads * Mail hook, for grabbing mail bags without stopping a train * Meat hook, for hanging up meat or carcasses of animals in butcheries and meat industry * Prosthetic hook or transradial prosthesis, part of a prosthetic arm for amputees * Purse hook, used to keep a woman's purse from touching the floor * Shepherd's hook (or crook), a staff used in herding sheep or other animals * Siege hook, an Ancient Roman weapon used to pull stones from a wall during a siege * Tailhook, used by aircraft to snag cables in order to slow down more quickly 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hook」の詳細全文を読む スポンサード リンク
