Barbed wire (also called barb wire) is a kind of wire that is used to make cheap fences. It has sharp metal points (barbs), which make climbing over it difficult and painful. Barbed wire was invented in 1867 in the United States by Lucien B. Smith. Barbed wire can be used by many countries in military field, prisons, detention houses, government buildings and other national security facilities.
