Although numbers increased exponentially in the last century, poaching has been occurring since 1200 BC. The horns were once shaped as wine cups, and the thick skin to manufacture armour for soldiers, belts and even crowns in China. In the Middle East the horns were carved to make the handles of ceremonial daggers known as Jambiyas.
