The medieval armorer had to be a combination of scientist toolmaker, chemist, metallurgist, engineer and artist. He was highly skilled and worked with wood and leather as well as metals. An armorer also had to understand mathematics and geometry. Much of his work revolved around high-end blacksmithing. Because he did custom work and produced high quality armor for nobles and knights, he was paid more money than a blacksmith was. Each suit of armor was made to order and would fit that person exactly. If any part of the suit of armor was damaged in battle, the armorer would repair it. In time of war an armorer also made armor for soldiers.
