Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved/bent back or has a deeply grooved indentation, which serves to grab, latch or in any way attach itself onto another object. The hook's design allows traction forces to be relayed through the curved/indented portion to and from the proximal end of the hook, which is either a straight shaft (known as the hook's ''shank'') or a ring (sometimes called the hook's "''eye''") for attachment to a thread (yarn), thread, rope or chain, providing a reversible attachment between two objects. In many cases, the distal end of the hook is sharply pointed to enable penetration into the target material, providing a firmer anchorage. Some hooks, particularly fish hooks, also have a ''barb'', a backwards-pointed projection near the pointed end that functions as a secondary "mini-hook" to catch and trap surrounding material, ensuring that the hook point cannot be easily pulled back out once e ...

Fish Hook
A fish hook or fishhook, formerly also called an angle (from Old English ''angol'' and Proto-Germanic ''*angulaz''), is a hook used to catch fish either by piercing and embedding onto the inside of the fish mouth (angling) or, more rarely, by impaling and snagging the external fish body. Fish hooks are normally attached to a line, which tethers the target fish to the angler for retrieval, and are typically dressed with some form of bait or lure that entices the fish to swallow the hook out of its own natural instinct to forage or hunt. Fish hooks have been employed for millennia by fishermen to catch freshwater and saltwater fish. There is an enormous variety of fish hooks in the world of fishing. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the hook. Fish hooks are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of arti ...

Hook-and-loop Fastener
Hook-and-loop fasteners, commonly known as Velcro (a Generic trademark, genericized trademark), hook-and-pile fasteners or touch fasteners are versatile fastening devices that allow two surfaces to be repeatedly attached and detached with ease. Invented in the mid-20th century, they are widely used in clothing, accessories, and various industrial and consumer applications. The fastener consists of two complementary components: one with tiny hooks and the other with soft loops. When pressed together, the hooks catch the loops, creating a secure but temporary bond. The fasteners can be separated by peeling or pulling the surfaces apart, often producing a distinctive ripping sound. History The original hook-and-loop fastener was conceived in 1941 by Swiss engineer George de Mestral, which he named velcro.The word Velcro is a portmanteau of two French words: "velours" meaning velvet, and "crochet" meaning hook. The idea came to him one day after he returned from a hunting trip wi ...

Crochet Hook
A crochet hook (or crochet needle) is an implement used to make loops in thread or yarn and to interlock them into crochet stitches. It is a round shaft pointed on one end, with a lateral groove behind it. The point eases the insertion of the hook through the material being crocheted and the groove makes it possible to pull a loop back through the material. The shaft is then divided into a working area that determines the hook's nominal diameter and ensures the uniform sizing of the loops formed on it, and a handle. Construction Crochet appeared as a distinct textile arts, textile art during the early 19th century, and many crochet hooks survive from that period. These can be sorted into two groups, the one with thin steel hooks that are set into separate handles, and the other including single-piece hooks made in a variety of materials. The distinction between steel and other hooks persists to the present day, although all are now commonly of single-piece construction. A variety ...

Hook (hand Tool)
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 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. Dockwork The longshoreman's hook was historically used by longshoremen (stevedores). Before the age of containerization, freight was moved on and off ships with extensive manual labor, and the longshoreman's hook was the basic tool of the dockworker. The ho ...

Dress Hook
A dress hook is a decorative clothing accessory of the medieval and Tudor periods used to fasten outer garments or to drape up skirts. Made of base metal or precious silver and silver-gilt, dress hooks are documented in wills and inventories, and surviving hooks have been identified in the archaeological record throughout England. "Dress hook" is the modern specialist terminology. In historical records, these items are referred to simply as "hooks", and context may be needed to differentiate them from hook-and-eye closures, which were also used in large quantities, in both base and precious metals, in the 15th and 16th centuries. Usage Documentary evidence suggests that dress hooks were often owned in pairs. Dress hooks were used to draw up skirts, either to keep them out of the muck of the street or to display the rich fabric of the garment beneath, and may also have been used to fasten garments or simply as decoration. At the time of her death in 1509, the jewellery o ...

Cap Hook
A cap hook is a decorative hat ornament fashionable from the Late Middle Ages through the Tudor period, used to pin up or decorate men's hat brims. Cap hooks were made of gold, silver, or silver-gilt base metal, and might be decorated with jewels or Vitreous enamel, enamelling. Cap hooks could be purely decorative or could carry religious or symbolic meaning. The latter form are called ''enseignes'' and may be an evolution of the medieval pilgrim badge. Usage In the early 16th century, it became fashionable for men to wear multiple small cap hooks alongside a larger hat jewel on the turned-up brims of their hats. Study and identification Cap hooks were little studied until the UK Treasure Act 1996, Treasure Act of 1996 required the examination and assessment of such small objects when made of precious metals. A seminal cross-disciplinary study of silver-gilt hooks in the Journal of the Society of Antiquaries of London in 2002 differentiates cap hooks from other types of ...

Cargo Hook (helicopter)
A cargo hook is a device suspended below a helicopter and allows the transport of external loads during flight. Common terms for this operation include slingwork, underslung loads, external loadwork, and external load operations. Hook types Primary hooks Primary, or "belly", hooks are designed to mount directly to the airframe belly, i.e. underside, of a helicopter. Because they are attached to the fuselage, or "skin," of the aircraft, belly hooks are regulated by the various worldwide civil aviation authority, aviation regulatory agencies. In the United States, belly hooks are governed under Federal Aviation Administration (FAA) Federal Aviation Regulations, FAR Part 133. Belly hooks are designed, manufactured, and approved for use on specific aircraft models. Belly hooks that have been certified by the FAA receive a Type certificate#Supplementary/Supplemental Type Certificate (STC), Supplemental Type Certificate (STC) that describes the aircraft models that are authorized ...

Bagging Hook
A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting or reaping grain crops, or cutting succulent forage chiefly for feeding livestock. Falx was a synonym, but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge. Since the beginning of the Iron Age hundreds of region-specific variants of the sickle have evolved, initially of iron and later steel. This great diversity of sickle types across many cultures can be divided into smooth or serrated blades, both of which can be used for cutting either green grass or mature cereals using slightly different techniques. The serrated blade that originated in prehistoric sickles still dominates in the reaping of grain and is even found in modern grain-harvesting machines and in some kitchen knives. History Pre-Neolithic The development of the sickle in Mesopotamia can be traced ...

Flesh-hook
270px, The Dunaverney flesh-hook, Bronze Age Ireland Flesh-hook is a term for a variety of archaeological artifacts which have metal hooks and a long handle, or socket for a lost wooden handle. Though the term may be applied to objects from other times and places, it is especially associated with the European Bronze Age and Iron Age. The metal shaft divides to form between two and five hooks with some sort of sharpened end. The purposes of the objects probably include pulling meat out of a pot or hides out of tan-pits. Some are plain in design but many are elaborately decorated, and if related to food, are clearly for the feasting hall rather than the kitchen (if such a distinction existed); some have been found with cauldrons and other large vessels. Some Bronze Age types are regarded as ritual objects, perhaps never actually used for a practical purpose. The division and serving of meat at feasts and after sacrifices was a matter of great social significance, and some ten ...

Grappling Hook
A grappling hook or grapnel is a device that typically has multiple hooks (known as ''claws'' or ''flukes'') attached to a rope or cable; it is thrown, dropped, sunk, projected, or fastened directly by hand to where at least one hook may catch and hold on to objects. Generally, grappling hooks are used to temporarily secure one end of a rope. They may also be used to dredge for submerged objects. The device was invented by the Romans in approximately 260 BC. The grappling hook was originally used in naval warfare to catch ship rigging so that it could be boarded. Design A common design has a central shaft with a hole ("eye") at the shaft base to attach the rope, and three or four equally spaced hooks at the end, arranged so that at least one is likely to catch on some protuberance of the target. Some modern designs feature folding hooks to resist unwanted attachment. Most grappling hooks are thrown by hand, but some used in rescue work are propelled by compressed air (e.g. ...
