Bondage, in the BDSM subculture, is the practice of consensually tying, binding, or restraining a partner for erotic, aesthetic, or somatosensory stimulation. A partner may be physically restrained in a variety of ways, including the use of rope, cuffs, bondage tape, or self-adhering bandage.
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.
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation, with all other translations or rotations prevented; thus a hinge has one degree of freedom. Hinges may be made of flexible material or moving components. In biology, many joints function as hinges, such as the elbow joint.
Bondage cuffs are restraints designed for use in sexual bondage situations. Compared to conventional handcuffs, they are wide wrist and ankle restraints generally made of leather, often padded with soft leather or fake fur. Bondage cuffs may be fastened at the wrists and/or ankles by a locking mechanism, by a buckle or by velcro. They are secured around the wrist or ankle, and the cuffs may then be attached to each other or another object.
A lock is a mechanical or electronic fastening device that is released by a physical object, by supplying secret information, by a combination thereof, or it may only be able to be opened from one side, such as a door chain.
Public humiliation or public shaming is a form of punishment whose main feature is dishonoring or disgracing a person, usually an offender or a prisoner, especially in a public place. It was regularly used as a form of judicially sanctioned punishment in previous centuries, and is still practiced by different means in the modern era.
A deadbolt or deadlock is a type of lock morticed into a wooden door. Then, using a key from either side of the door, a bolt is thrown into the door frame, thus securing the door. It is distinct from a spring bolt lock because a deadbolt can only be opened by a key or handle. The more common spring bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key, as well as make the door more resistant to forced entry. A deadbolt is often used to complement a spring-bolt lock on an entry door to a building.
Cock and ball torture (CBT) is a sexual activity involving the application of pain or constriction to the male genitals. This may involve directly painful activities, such as genital piercing, wax play, genital spanking, squeezing, ball-busting, genital flogging, urethral play, tickle torture, erotic electrostimulation, kneeing or kicking. The recipient of such activities may receive direct physical pleasure via masochism, or emotional pleasure through erotic humiliation, or knowledge that the play is pleasing to a sadistic dominant. Many of these practices carry significant health risks.
A lever tumbler lock is a type of lock that uses a set of levers to prevent the bolt from moving in the lock. In the simplest form of these, lifting the tumbler above a certain height will allow the bolt to slide past.
Legcuffs are physical restraints used on the ankles of a person to allow walking only with a restricted stride and to prevent running and effective physical resistance. Frequently used alternative terms are leg cuffs, (leg/ankle) shackles, footcuffs, fetters or leg irons. The term "fetter" shares a root with the word "foot".
A crash bar is a type of door opening mechanism which allows users to open a door by pushing a bar. While originally conceived as a way to prevent crowd crushing in an emergency, crash bars are now used as the primary door opening mechanism in many commercial buildings.
Safe-cracking is the process of opening a safe without either the combination or the key.
Plastic handcuffs are a form of physical restraint for the hands made of plastic straps. They function as handcuffs but are cheaper and easier to carry than metal handcuffs, and they cannot be reused. The device was first introduced in 1965.
A latch or catch is a type of mechanical fastener that joins two objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a keeper or strike.
A keypad is a block or pad of buttons set with an arrangement of digits, symbols, or alphabetical letters. Pads mostly containing numbers and used with computers are numeric keypads. Keypads are found on devices which require mainly numeric input such as calculators, television remotes, push-button telephones, vending machines, ATMs, point of sale terminals, combination locks, safes, and digital door locks. Many devices follow the E.161 standard for their arrangement.
Speedcuffs are a model of handcuff characterised by their rigid grip between the two ratchet cuffs. Their rigid design and the inclusion of a grip makes them effective for gaining control over a struggling prisoner, even if only one cuff has been applied. They are standard issue for most police forces within the United Kingdom.
Locksport is the sport or recreation of defeating locking systems. Its enthusiasts learn a variety of skills including lock picking, lock bumping, and a variety of other skills traditionally known only to locksmiths and other security professionals. Locksport followers enjoy the challenge and excitement of learning to defeat all forms of locks, and often gather together in sport groups to share knowledge, exchange ideas, and participate in a variety of recreational activities and contests.
A belly chain is a physical restraint worn by prisoners, consisting of a chain around the waist, to which the prisoner's hands may be chained or cuffed. Sometimes the ankles are also connected by means of longer chains.
The term torture trade refers to the manufacture, marketing, and export of tools commonly used for torture, like restraints and high-voltage electro-shock weapons. In 2001, Amnesty International released a report on "Stopping the Torture Trade".
A handcuff cover is a plastic or metal cover that can be placed over a pair of handcuffs. It consists of a hinged, box-like assembly locked over the handcuff chain, wristlets and keyholes.
