Barbed Wire? You mean dental floss?
The Story of Barbed Wire
Joseph Glidden invented barbed wire fence by using a coffee mill to make sharp barbs. He placed the barbs along a wire and twisted a second wire around the first. He received the patent for the wire in 1874. But soon people started to battle him about whether he actually invented it. He won and started the Barb Fence Company in DeKalb, Illinois making him the mother load. By the time he died he was one of the richest men in America.
Now and Then
Barbed Wire was created to keep animals or mostly cattle in a contained area. Before barbed wire cattle would walk through the wire fence, breaking it, because there was no trees or stones to build barriers. Barbed wire is still the same today, the same design and same purpose. Although barbed wire is also used for fencing to keep people out or to keep people in. Another benefit of barbed wire is nearly the same price as normal wire.
