David Baker: "The Mongol-style bow was a composite of horn, wood, and sinew, laminated and wrapped in hide. Unstrung, the bow forms a shape like a C. When strung you can see the deep recurve and 'ears' that give the bow its bower. The Mongols used bows of different weights depending on the situation. On horseback, the bow would be around a 65- to 70-pound pull, while on the ground bows of 120 pounds could be used. They also developed many different types of arrow heads to use, depending on the situation."
