Tentetsutou, The Sword Of Heaven: A Katana Forged From An Iron Meteorite

This is 天鉄刀 (Tentetsutou, The Sword Of Heaven), a traditional Japanese katana forged entirely from an iron-alloy meteorite. Obviously, it’s the perfect weapon for a space ninja like myself. “You are not a space ninja.” Then how am I writing this FROM THE MOON? “You aren’t.” I could be. “But you aren’t.” Man, I hate playing pretend with grownups.
