The introduction of barbed razor wire
Barbed razor wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans. The term razor wire has generally been used to describe barbed tape products. But razor wire is much sharper than the standard barbed wire. However, the points are very sharp and made to rip and grab onto clothing and flesh.
The multiple blades of a razor wire fence are designed to inflict serious cuts on anyone attempting to climb through, and therefore it can build a strong psychological deterrent effect. Razor wire contains a core hardened steel strip that is often under tension, so if cut, the recoil could cause the wire to unfurl and lash out, striking the cutter.
Barbed wire became common in the American West in the 1870s, and it was first found wide use in fortifications in World War I. Barbed tape was first manufactured by Germany as an expedient measure during a shortage of wire during World War I. Since it was simply punched out of a rolled ribbon of steel tape, it could be manufactured much more quickly. This early barbed tape had triangular barbs and no reinforcing wire. Consequently, it was more difficult to cut with ordinary wire cutters, easier to cut with shears, and was generally of lower tensile strength.
From the early 1970s, unreinforced barbed tape was commonly used in perimeter barriers of US prisons.
In the early 1980s, several manufacturers began offering barbed tape with an embedded reinforcing wire and the product has been the subject to a patent dispute. Early brand names of reinforced barbed tape included Man Barrier and Razor Ribbon.
Above all, there are the history and introduction of barbed razor wire. Hope can help you.
