I’ve recently been following a channel on Youtube called Hand Tool Rescue and it’s been fascinating to learn the history of antique hand and power tools.  I didn’t realize how long ago many power tools – most of which we still use today – were created.  It’s perhaps even more fascinating to watch a rusty old machine that hasn’t been used in decades be completely restored to working condition. His videos don’t have voice overs, so you have to pay close attention to his methods, but every step of the process is shown.
