This iron dagger made my list of favorite items from King Tutankhamun's tomb because it looked commonplace compared to everything else buried with the young king. As like many things in history and art, however, it turns out that there is more to this blade than meets the eye. Researchers have recently discovered that the blade, like the beetle preceding it on my list, finds its beginning in outer space. The iron is actually meteorite, formed into a weapon with an origin that's literally out of this world.
