Handcuff
Handcuffs are restraining devices designed to secure a person’s wrists together, preventing movement of the hands. They are commonly used by law enforcement officers, security personnel, and military forces to detain individuals.
Handcuffs are typically made of metal and consist of two rings or cuffs that can be locked around the wrists, connected by a short chain, hinge, or rigid bar. Most modern handcuffs use a ratchet-and-lock mechanism, which allows them to be adjusted to fit different wrist sizes and requires a key for release.
In addition to law enforcement, handcuffs are sometimes used in personal security, self-defense, and even as props in entertainment and fashion. However, their primary function remains to ensure the controlled restraint of an individual in custody.
