Joseph Glidden’s Barbed Wire

Origin
Joseph Glidden was an American farmer who patented barbed wire, a product that forever altered the development of the American West. His invention, a steel wire fencing with many pointy ends, was meant to cause injury and force cattle and people to stay on their respective sides of the fence. Its invention helped end the free range care of cattle in the American west. It is also used in war and security as an obstacle to defend from infiltration.

Effects
The few pieces of barbed wire can duplicate themselves into many longer strands to place around a building or specific area. The spikes will dig deep into any flesh until the person backs away from it. With this effect, the wire effectively traps people within a designated area.
