The goldwork was done in the mid-19th century.
The grip is made up; the wooden block is decorated with the wristplate from an 18th century armguard. The notion of tourist trinkets is an ancient one in the Middle East and Central Asia. Britain and France, and later, Russia, maintained a presence in Iran for much of the 19th century. It may well have been fabricated as a gift or memento.
