Sun Jifa, a farmer from China's northern Jilin province, lost both his arms after an explosive fishing device went off prematurely. And since a low-grade set of prosthetic arms he bought weren't any good in his farming activities and he was unable to afford a pair of expensive ones, he went all DIY on it.
He spent eight years crafting and perfecting his own steel bionic arms from scratch with little direction but his own intuition, and after becoming somewhat of a local celebrity for doing it, he started building them for other people too. So far he has built around 1,000 of them.
