Today, it's simple to drill a hole. Just grab your power drill, pop on the right bit, and poof! You have a hole. Prior to the invention of power tools, all that work had to be done by hand. This hand drill from the 19th century illustrates how much work was needed to do something as simple as making a hole. And of course, the harder the surface, the harder you had to work to turn the drill and make any progress!
