Kaiu Yasunori

Kaiu no Kenru Yasunori was a Crab swordsmith of the 11th century, who developed a new steel alloy while tinkering in his forge. Quite by accident, they discovered that a mix of various ores and refined metals made a steel that was both lightweight and strong but lacked the beauty of traditional Rokugani steel. Soon they began creating massive two-handed swords and axes for use in defending the Kaiu Wall. Yasunori steel weapons were popular among Crab samurai who appreciated a sturdy, well-made blade and cared little for aesthetics.
