Handcuffs
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
Handcuffs are restraint devices designed to secure an individual's wrists close together. They comprise two parts, linked together by a chain, a hinge, or rigid bar. Each half has a rotating arm which engages with a ratchet that prevents it from being opened once closed around a person's wrist. Without the key, the handcuffs cannot be removed and so the handcuffed person is unable to move his or her wrists more than a few centimetres/inches apart, making many tasks difficult or impossible. This is usually done to prevent suspected criminals from escaping police custody.

There are three main types of contemporary metal handcuffs: chain (cuffs are held together by a short chain), hinged (since hinged handcuffs permit less movement than a chain cuff, they are generally considered to be more secure), and rigid solid bar handcuffs. While bulkier to carry, rigid handcuffs permit several variations in cuffing. Hiatts Speedcuffs are rigid handcuffs used by most police forces in the United Kingdom. Both rigid and hinged cuffs can be used one-handed to apply pain-compliance/control techniques that are not workable with the chain type of cuff. Various accessories are available to improve the security or increase the rigidity of handcuffs, including boxes that fit over the chain or hinge and can themselves be locked with a padlock.
In 1933 the Royal Canadian Mounted Police used a type called "Mitten Handcuffs" to prevent criminals from being able to grab an object like the officer's gun. While used by some in law enforcement it was never popular.[1]
Handcuffs may be manufactured from various metals, including carbon steel, stainless steel and aluminium, or from synthetic polymers.
Sometimes two pairs of handcuffs are needed to restrain a person with an exceptionally large waistline because the hands cannot be brought close enough together; in this case, one cuff on one pair of handcuffs is handcuffed to one of the cuffs on the other pair, and then the remaining open handcuff on each pair is applied to the person's wrists. Oversized handcuffs are available from a number of manufacturers.
The National Museum of Australia has a number of handcuffs in its collection dating from the late 19th and early 20th centuries. These include'T'-type 'Come Along', 'D'-type and 'Figure-8' handcuffs.[2]
Double locks
Handcuffs with double locks have a detent which when engaged stops the cuff from ratcheting tighter to prevent the wearer from tightening them. Tightening could be intentional or by struggling; if tightened, the handcuffs may cause nerve damage or loss of circulation. Also some wearers could tighten the cuffs to attempt an escape by having the officer loosen the cuffs and attempting to escape while the cuffs are loose. Double locks also make picking the locks more difficult.
There exist three kinds of double locks as described in a Smith & Wesson brochure:
- Lever lock
- Movement of a lever on the cuff causes the detent to move into a position that locks the bolt. No tool is required to double lock this type of cuff.
- Push pin lock
- A small peg on the key is inserted endwise into a hole to engage the detent.
- Slot lock
- These also are actuated with a peg, but in this case it is inserted into a slot and moved sideways to engage the detent.
Double locks are generally disengaged by inserting the key and rotating it in the opposite direction from that used to unlock the cuff.
Plastic handcuffs

Plastic restraints, known as wrist ties, riot cuffs, plasticuffs, flexicuffs, flex-cuffs, tri-fold cuffs, zapstraps, zipcuffs, or zip-strips, are lightweight, disposable plastic strips resembling electrical cable ties. They can be carried in large quantities by soldiers and police and are therefore well-suited for situations where many may be needed, such as during large-scale protests and riots. In recent years, airlines have begun to carry plastic handcuffs as a way to restrain disruptive passengers. Disposable restraints could be considered to be cost-inefficient; they cannot be loosened, and must be cut off to permit a restrained subject to be fingerprinted, or to attend to bodily functions. It is not unheard of for a single subject to receive five or more sets of disposable restraints in his or her first few hours in custody.
However, aforementioned usage means that cheap handcuffs are available in situations where steel ones would normally lie unused for long times. Recent products have been introduced that serve to address this concern, including disposable plastic restraints that can be opened or loosened with a key; more expensive than conventional plastic restraints, they can only be used a very limited number of times, and are not as strong as conventional disposable restraints, let alone modern metal handcuffs. In addition, plastic restraints are believed by many to be more likely to inflict nerve or soft-tissue damage to the wearer than metal handcuffs.
Legcuffs
On occasions when a suspect exhibits extremely aggressive behavior, leg irons may be used as well; sometimes the chain connecting the leg irons to one another is looped around the chain of the handcuffs, and then the leg irons are applied, resulting in the person being "hog-tied". In a few rare cases, hog-tied persons lying on their stomachs have died from positional asphyxia, making the practice highly controversial, and leading to its being severely restricted, or even completely banned, in many localities.
Keys
Most modern handcuffs in Canada, the United States, the United Kingdom and Latin America can be opened with the same standard universal handcuff key. This allows for easier transport of prisoners. However, there are handcuff makers who use keys based on different standards. Maximum security handcuffs require special keys. Handcuff keys usually do not work with thumbcuffs. The Cuff Lock handcuff key padlock uses this same standard key.
In addition to the Universal handcuff key, a few modified designs exist, including a key that has been molded to fit behind an officer's badge (colloquially known as "The New York Tuning Fork" - U.S. Patent 607,305).
Hand positioning
In the past, police officers typically handcuffed an arrested person with his or her hands in front, but since approximately the mid-1960s behind-the-back handcuffing has been the standard. The vast majority of police academies in the United States today also teach their recruits to apply handcuffs so that the palms of the suspect's hands face outward after the handcuffs are applied.[citation needed] The Jacksonville, Florida Police Department, the Los Angeles County Sheriff's Department and others are notable exceptions, as they favor palms-together handcuffing.[citation needed] This helps prevent radial neuropathy or handcuff neuropathy during extended periods of restraint. Suspects are handcuffed with the keyholes facing up (away from the hands) to make it difficult to open them even with a key or improvised lock-pick.
Because a person's hands are used in breaking falls, being handcuffed introduces a significant risk of injury if the prisoner trips or stumbles, in addition to injuries sustained from overly tight handcuffs causing handcuff neuropathy. Police officers having custody of the person need to be ready to catch a stumbling prisoner.
As soon as restraints go on, the officer has full liability. The risk of the prisoner losing balance is higher if the hands are handcuffed behind the back than if they are handcuffed in front; however, the risk of using fisted hands together as a weapon increases with hands in front.
Some prisoners being transported from custody to outside locations, for appearances at court, to medical facilities, etc., will wear handcuffs augmented with a belly chain. In this type of arrangement a metal, leather, or canvas belt is attached to the waist, sometimes with a locking mechanism. The handcuffs are secured to the belly chain and the prisoner's hands are kept at waist level. This allows a relative degree of comfort for the prisoner during prolonged internment in the securing device, while providing a greater degree of restriction to movement than simply placing the handcuffs on the wrists in the front.
Escaping
Since handcuffs are only intended as temporary restraints, they are not the most complicated of locks.[3] This is why escaping from handcuffs is a common stunt performed by magicians or skilled criminals, perhaps most famously Harry Houdini.
There are several ways of escaping from handcuffs:
- slipping hands out when the hands are smaller than the wrist
- lock picking
- releasing the pawl with a shim
- opening the handcuffs with a duplicate key, often hidden on the body of the performer before the performance.
The above methods are often used in escapology. As most people's hands are larger than their wrists, the first method was much easier before the invention of modern ratchet cuffs, which can be adjusted to a variety of sizes. Modern handcuffs are generally ratcheted until they are too tight to be slipped off the hands. However, slipping out of ratchet cuffs is still possible. During his shows, Harry Houdini was frequently secured with multiple pairs of handcuffs. Any pair that was too difficult to be picked was placed on his upper arms. Being very muscular, his upper arms were far larger than his hands. Once he had picked the locks on the lower pairs of handcuffs, the upper pair could simply be slipped off.
It is also technically possible to break free[4] from handcuffs by applying massive amounts of force from one's arms to cause the device to split open or loosen enough to squeeze one's hands through; however, this takes exceptional strength (especially with handcuffs made of steel). This also puts an immense amount of pressure on the biceps and triceps muscles, and when tried by suspects (even unsuccessfully) can lead to injury, including bruising around the wrists, or tearing the muscles used (including pulling them off their attachments to the bones).[citation needed]
Another common method of escaping (or attempting to escape) from being handcuffed behind the back, is that one would, from a sitting or lying position, bring one's legs up as high upon one's torso as possible, then push one's arms down to bring the handcuffs below one's feet, finally pulling the handcuffs up using one's arms to the front of one's body. This can lead to awkward or painful positions depending on how the handcuffs were applied, and typically requires a good amount of flexibility. It can also be done from a standing position, where, with some degree of effort, the handcuffed hands are slid around the hips and down the buttocks to the feet; then sliding each foot up and over the cuffs. These maneuvers, and the reverse (otherwise impossible) maneuver of bringing the handcuffed hands up behind the back and forwards over the head and then down in front, can be done fairly easily by some people who were born without collarbones because of the inherited deformity called cleidocranial dysostosis.
From this position, one has a better chance of attempting to use a tool (such as a shim or lockpick) to work one's way out of the handcuffs.
National regulations regarding depiction of handcuffed people
In Japan, if someone is photographed or filmed while handcuffed, their hands have to be pixelated if it is used on TV or in the newspapers. This is because Kazuyoshi Miura who had been arrested brought a successful case to court arguing that being pictured in handcuffs implied guilt, and had prejudiced the trial.[5]
Similarly, in France, a law prohibits media from airing images of people in handcuffs, or otherwise restrained, before they have been convicted by a court.[6][7]
In Hong Kong, people being arrested and led away in handcuffs are usually given the chance by the policemen to have their heads covered by a black cloth bag.
Use in BDSM
Police handcuffs are sometimes used in sexual bondage and BDSM activities. This is potentially unsafe, because they were not designed for this purpose, and their use can result in nerve injury (handcuff neuropathy) or other tissue damage. Bondage cuffs were designed specifically for this application. They were designed using the same model of soft restraints used on psychiatric patients because they can be worn for long periods of time. Many such models can be fastened shut with padlocks.
Metaphorical uses
Handcuffs are familiar enough for the word to be used in metaphors, e.g.:
- Golden handcuffs – an incentive given to an employee by a firm, most or all of which must be repaid to the company if the employee leaves the firm within a specified period of time.
- As a verb, meaning to be kept from doing something by another's action or inaction – "He said that his computer work is handcuffed by his internet provider's refusal to accept .zip files."
- In fantasy football, one strategy is to have both a star player and his backup, or "handcuff", on a team's roster of players. If the star is injured, the handcuff will be his likely replacement.
