Link chain in the context of "Jewellery chain"

Handcuffs are restraint devices designed to secure an individual's wrists in proximity to each other. They comprise two parts, linked together by a chain, a hinge, or rigid bar. Each cuff has a rotating arm which engages with a ratchet that prevents it from being opened once closed around a person's wrist. Without a key, handcuffs cannot be removed without specialist knowledge, and a handcuffed person cannot move their wrists more than a few centimetres or inches apart, making many tasks difficult or impossible.

Handcuffs are frequently used by law enforcement agencies worldwide to prevent suspected criminals from escaping from police custody.

Hardware stores (in a number of countries, "shops"), sometimes known as DIY stores, sell household hardware for home improvement including: fasteners, building materials, hand tools, power tools, keys, locks, hinges, chains, plumbing supplies, electrical supplies, cleaning products, housewares, tools, utensils, paint, and lawn and garden products directly to consumers for use at home or for business. Many hardware stores have specialty departments unique to its region or its owner's interests. These departments include hunting and fishing supplies, plants and nursery products, marine and boating supplies, pet food and supplies, farm and ranch supplies including animal feed, swimming pool chemicals, homebrewing supplies and canning supplies.

A pectoral cross or pectorale (from the Latin pectoralis, "of the chest") is a cross that is worn on the chest, usually suspended from the neck by a cord or chain. In ancient history and the Middle Ages, pectoral crosses were worn by both clergy and laity. By the Late Middle Ages, the pectoral cross came to be a special indicator of position worn by bishops. In the Roman Catholic Church, the wearing of a pectoral cross remains restricted to popes, cardinals, bishops and abbots. In Eastern Orthodox Church and Byzantine Catholic Churches that follow a Slavic Tradition, priests also wear pectoral crosses, while deacons and minor orders do not. The modern pectoral cross is relatively large, and is different from the small crosses worn on necklaces by many Christians. Most pectoral crosses are made of precious metals (platinum, gold or silver) and some contain precious or semi-precious gems. Some contain a corpus like a crucifix while others use stylized designs and religious symbols.

In many Christian denominations, the pectoral cross symbolizes that the person wearing it is a member of the clergy, or that the wearer is a member of the higher or senior clergy. However, in many Western churches there are an increasing number of laypeople who choose to wear some form of a cross around their neck.
