Using electrolysis on this leatherman skeletool brought it back from the dead. The tool was lost two years ago while wendy was planting trees. It slipped out of her overalls and we were unable to locate it. While planting trees this week the tool was found in unusable condition. I put it into a bath with a chunk of metal and connected it to a irobot roomba 22V battery charger. Within two days the tool was working again.
