Concertina razor barbed wire is the most common type of razor barbed wire. It is formed in large coils which can be expanded like a concertina. In conjunction with plain barbed wire and steel pickets, it is used to form military wire obstacles.
 
Concertina Razor coils is supplied typically in single coils or crossed spiral coils. Each spiral circle is joined by three, five or seven rows of connector clips, depending on the diameter of the circle. This condenses the spacing of the spirals. The clip is made of 1.5-2mm thick and overall 10mm wide hot – galvanized sheet metal or stainless steel. This makes the coil very difficult to open, even with a special tool. The diameter of the circle is reduced by 5-10% after opening.
