David Baker: "The Mongols used a type of armor called Lamellar, made up of small steel plates around 1-inch-by-1 3/4 inches. Each plate has six holes punched in it so the plates can be sewn together. For the show, we only had a few days to re-create the Mongol armor, and in trying to stay true to the original style of manufacturing Lamellar, we hand cut around 500 individual plates, punched six holes in each one and then laced them together, creating a very flexible sheet of steel plates. The great thing about Lamellar is that it gives you a lot of protection without giving up too much flexibility. We did several tests off camera and could not cut or get an arrow to penetrate the armor. In my opinion, short of full plate armor, Lamellar is by far the strongest."
