A swordstick or cane-sword is a cane containing a hidden blade or sword. The wood of the cane therefore functions as the blade's scabbard, while the handle and head function as the hilt. The term is typically used to describe European weapons from around the 18th century, but similar devices have been used throughout history, notably the Roman dolon, the Japanese shikomizue and the Indian gupti.
Use of the European swordstick contrasts against the martial art of cane-fighting, the use of unmodified walking sticks for non-lethal self-defense.
