Barbed wire

Barbed wire (also called barb wire ) is a kind of wire that is used to make cheap fences . It has sharp metal points ( barbs ), ^[1] which make climbing over it painful.

The first patent in the United States for barbed wire was issued in 1867 to Lucien B. Smith of Kent, Ohio , who is regarded as the inventor. ^[2]^[3] Joseph Glidden of DeKalb, Illinois , received a patent for the modern invention in 1874 after he made his own modifications to previous versions.

It was first used for controlling cattle and later in trench warfare , and in other places to stop people. Improvements led to the creation of Razor wire, in the 1960's.
