Sun Jifa, from Jilin province, China, made his own homebrew prosthetic arms after losing his own in a "fishing related explosion." The hospital that treated him after the accident recommended a set of expensive factory-made limbs that were out of his price-range, so the 51-year-old made his own. He says that the steel is heavy and is too cold in the winter and too hot in the summer. But they are still evidently superior to nothing at all, which seems to have been his other option.
