Sun Jifa, 51, lost both his hands when a bomb he was creating for blast fishing in Guanmashan, northern China, exploded. Sun could not afford the hospital’s prosthetic limbs after the explosive for blast fishing detonated prematurely, but he desperately needed his hands to work on the family farm. He spent eight years making prototypes before finally creating a pair of metal hands which can grip and hold items thanks to a series of wires and pulleys inside the shell. Sun said, “I made this from scrap metal for virtually nothing. There is no need to pay hospitals a fortune.”
