Concertina Coils

Concertina wire is a type of barbed wire or razor wire of metal strips with sharp edges whose purpose is to prevent passage by humans or animals. The multiple blades of a razor wire fence are designed to inflict serious cuts on anyone attempting to climb through and therefore have a strong psychological effect. Concertina wire packs flat for ease of transport, but can then be deployed as an obstacle much more quickly than ordinary barbed wire.
