Even though we live in a world where guns are the most deadly and popular weapons, it looks like swords will never truly go out of style. This unique katana was aptly named Sword of Heaven, and it was created by a Japanese master swordsmith named Yoshindo Yoshiwara. The interesting thing about Tentetsutou (its Japanese name) is that it was forged from iron that was extracted from a meteorite fragment. The meteorite in question is the Gibeon, which formed about 4 billion years ago and crashed in Namibia in ancient times.
The Sword of Heaven is currently stored at the Chiba Institute of Technology in the Tokyo Skytree tower, where it can be admired by visitors permanently alongside a sample of the material used in its construction. Considering the fact that it was made from a material that formed outside of our planet, this sword is one of Japan’s most prized artifacts.
