Razor Wire is a mesh of metal strips with sharp edges whose purpose it is to prevent passage by human beings. Although it is sharper than the barbs of barbed wire, it is not actually razor sharp. Getting past razor wire without tools is considerably slower, giving security forces much more time in which to respond.
It can be used as fences for highways, railways, roads, hills or mountains, farms, and various constructions, also as isolation screens. The manufacturer recommends that all "razor coil", "razor spike", ?razor wire÷ and "ultra barrier" products are potentially dangerous and should be attached to walls and fences at a minimum height of 8 feet. The installed material must avoid any and all contact with pedestrian traffic and be installed in a highly visible manner.
