Guan Yu's Green Dragon Saber

The brothers expressed their gratitude, and the merchants took their leave. Then blacksmiths were summoned to forge weapons. For Liu Bei they made a pair of ancient swords; for Guan Yu they fashioned a long-handled, curve blade called Green-Dragon Saber, which weighed a full one hundred pounds; and for Zhang Fei they created a ten-foot spear called Serpent Halberd. Each too had a helmet and full armor (Romance of the Three Kingdoms, Ch 1).
