Doing a professional's job or a tradesman's job is different from designing the tools they use to do these jobs. So it would be asking a non-carpenter to design whatever tool they need to get nails to go into wood. You'd probably end up with some caveman looking rock strapped to a stick and then it would evolve into something very similar to a hammer. The claw on the back to remove nails may or may not be combined with the hammer.
