The Rampuri (रामपूरी चाकू) is an Indian gravity knife with a single-edged blade roughly 9 to 12 inches (23 to 30 cm) long.
The royal bladesmiths of local Nawabs of Rampur started making knives after the popularization of firearms after the 18th century.
[citation needed] The Rampuri is still in use today as a criminal weapon[3] by the local Indian Mafia, although locally made guns and sophisticated automatic pistols have largely taken their place.
However, in the mid 1990s, the Government of Uttar Pradesh banned making such knives longer than 4.5 inches (11 cm) in blade length, which led to a drop in popularity of the knife.
