Razor wire

Barbed tape, or razor wire, is a security barrier made of metal strips with sharp edges, designed to deter unauthorized passage across a boundary.

Use

Due to its dangerous nature, razor wire/barbed tape and similar fencing/barrier materials are prohibited in some locales. Norway prohibits any barbed wire except in combination with other fencing, in order to protect domesticated animals from exposure.

Construction

Razor wire has a central strand of high tensile strength wire, and a steel tape punched into a shape with barbs. The steel tape is then cold-crimped tightly to the wire everywhere except for the barbs. Flat barbed tape is very similar, but has no central reinforcement wire. The process of combining the two is called roll forming.
