Käsirautat

Käsirautat, often translated as handcuffs, are restraint devices that secure a person's wrists together. They are typically made of metal, commonly steel or aluminum, and consist of two interlocking cuffs connected by a chain or a hinge. Each cuff has a swinging arm that ratchets into a toothed segment, allowing for adjustment to fit different wrist sizes. A key is usually required to unlock and release the cuffs.

Historically, restraint devices have been used for centuries to control individuals. Modern käsirautat evolved from earlier forms of shackles and manacles. Their primary purpose is to prevent individuals from escaping custody, harming themselves, or harming others. They are most commonly used by law enforcement officers and security personnel.

The use of käsirautat is subject to legal regulations in most jurisdictions, dictating when and how they can be applied. While effective for restraint, improper application can cause injury. There are also different types of käsirautat, including standard, rigid, and disposable plastic restraints, each with specific applications. Some specialized versions may include additional features like double locks to prevent further tightening after initial application. Their use is a significant aspect of law enforcement procedure and personal security.
