A keychain or key chain is a
small chain, usually made from
metal or plastic that connects
a small item to a key ring.
The length of a keychain
allows an item to be used more
easily than if connected
directly to a key ring. Some
key chains allow one or both
ends the ability to rotate,
keeping the keychain from
becoming twisted, while the
item is being used. A keychain
can also be a connecting link
between a key-ring and the
belt of an individual. It is
usually employed by personnel
whose job demands frequent use
of keys, such as a security
guard, prison officer,
janitor, or retail store
manager. The key chain ensures
that the keys remain attached
to the individual using them,
makes accidental loss less
likely, and saves on wear and
tear on the pockets of the user.
