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. Razor Wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans. Razor Wire is manufactured using a Central Core of high Tensile Wire - around which a tape of razor sharp barbs is machine crimped. The resulting razor wire is therefore exceedingly difficult to cut using hand tools. Razor Wire is very strong and reinforced with a steel coil which makes it very hard to bend, while the barbs have a piercing and gripping action.
