Piano wire is a specialized type of wire for use in piano strings. It is typically made from aluminium, copper, or brass. The diameter of the wire can range from .029 inches (0.74 mm) to .112 inches (2.84 mm).
Installation of piano wire should not be done with bare hands, as perspiration on the skin could lead to rusting. It can also be unwieldy, and lead to eye damage and lacerations if proper safety equipment such as goggles and gloves are not used.
Piano wire achieved notoriety in popular culture when it was featured in a "Piano Wire Watch" worn by S.P.E.C.T.R.E. assassin Donald "Red" Grant in the James Bond film From Russia With Love. The watch had a hidden tab that could be pulled out revealing a length of piano wire to be used as a garrote, referencing a torture execution tactic employed by the Nazis in the wake of the July 20 plot.
