Origin: The Green Steel Sword is a legendary blade from the Ming Dynasty novel Romance of the Three Kingdoms, renowned for its exceptional sharpness capable of slicing through iron with ease. The sword's scabbard bore a gold inscription reading “Qīng Gāng”. “Cao Cao possessed two peerless swords: the ‘Yitian’ and the ‘Qinggang’, collectively known as the unparalleled twin blades. He kept the Yitian for himself, while the Qinggang was entrusted to Xiahou En. It was later captured by Zhao Yun at the Battle of Changban.”
