Galvanized concertina wire

Concertina wire is a type of barbed wire or razor wire that is formed in large coils which can be expanded like a concertina. Each coil actually consists of two oppositely wound helices which support each other against crushing while allowing easy longitudinal movement. In conjunction with plain barbed wire and steel pickets, it is used to form military wire obstacles.

Concertina wire is sometimes mistakenly called constantine wire. "Constantine" probably came from a corruption/misunderstanding of "Concertina" and led to confusion with the Roman Emperor Constantine. This in turn has led to some people trying to differentiate between concertina wire and "constantine" wire by incorrectly assigning the latter term to what is commonly known as razor wire. In contrast to the double-helical construction of concertina wire, as shown being deployed by soldiers in the image, razor wire, or less correctly "constantine wire", consists of a single wire with projecting teeth periodically along its length.
