Razor Wire

Barbed tape or Razor Wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans. The name "Razor Wire" is a registered trademark of Allied Tube and Conduit Company, although through long usage the term is generally used to describe the barbed tape products of other manufacturers. Whilst razor wire is much sharper than the barbs of standard barbed wire, it is not actually razor sharp. Even so, the multiple bladed edges of a razor wire fence are designed to inflict serious cuts on anyone who attempts to climb through one, and therefore have a strong psychological deterrent effect.
