Razor wire is a type of fencing material made from sharp-edged metal strips. It is designed to deter intruders and enhance security around properties, such as prisons, military bases, and industrial sites. The sharp blades are typically spaced apart on a wire strand, making it difficult to climb over or cut through. This fencing is often used in combination with other security measures, such as chain-link fences or security cameras. Razor wire is effective in preventing unauthorized access, but it can also pose risks to animals and people if not properly marked or maintained.
