Home Defense With Brass Knuckles Is Possible?

Brass knuckles are a type of punching bag that dates back to the early 19th century. In those days, these were used by sailors as a form of self-defense on the high seas. The knuckle was lined with metal to protect against sword cuts or other forms of injury from enemies on board, and the mass of metal on the outside provided a further layer of protection for those inside.
