razor wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans. The term "razor wire", through long usage, has generally been used to describe barbed tape products. While razor wire is much sharper than the standard barbed wire, it is named after its appearance, but is not actually razor sharp. However, the points are very sharp and made to rip and grab onto clothing and flesh. Razor wire, also called razor barbed tape is a more aggressive and better intruder deterrent for elevations above fencing. Also known as Razor Tape, or Razor Strip, it can be used as a fencing itself, or used in the form of Razor Wire. Razor Tape can be made of stainless steel sheet or galvanized steel sheet. It is a good topping on fence to prevent intrusion.
