The bows are about as tall as a man and have a heavy enough draw-weight that only someone wearing Shardplate would be able to draw it fully. This has led to some calling them Shardbows. The fabrial ensures that the metal of the bow does not warp under the stress of being drawn. The arrows used with a grandbow are as thick as a three fingers, and quite long.
Grandbows were designed by Alethi artifabrians led by Navani Kholin during the War of Reckoning. They were often used during chasmfiend hunts to injure the creatures before the hunters moved in for the final kill. In 1173, Highprince Torol Sadeas used a grandbow to attack the chasmfiend that surprised the Alethi during a hunt, while Highprince Dalinar Kholin as well as Adolin and King Elhokar attacked it with their Shardblades.
Rock was able to draw and fire a Grandbow at the Battle of Thaylen Field and kill Meridas Amaram after he had joined with Yelig-nar. He is the only known person to be able to draw a Grandbow without the aid of Shardplate, though he was holding Stormlight at the time.
