I was unaware of that. I used to believe that a knife that wasn’t properly sheathed was the deadly. Cambyses II, a short-lived Persian emperor, passed away from an illness from a self-inflicted thigh wound in 522 BC. It appears that he excitedly mounted a horse and armed himself with his elegant short sword. It was coated in feces since he had just used it to kill the sacred Egyptian bull.
This exact sword in fact.
