razor 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.
