Concertina coil is a fusion of barbed and razor wires in the form of large coils which can be further expanded as an entangled concertina. These wires or coils are basically used for the military purpose of forming wired obstacles. The twofold cook’s garment fence contained a line of pickets with wires running corner to corner down to focus on the ground on either side of the fence. Even wires were appended to these diagonals. More detailed and considerable impediments could be shaped with different lines of stakes associated with wire running from side-to-side, back-to-front, and slantingly each conceivable way. Powerful as these hindrances were, their development took significant time; and they later came to be known as concertina coils.
