It's a book about the history of the screwdriver. Really it's an extra long feature article in book form. The author, a guy with a truly unpronounceable name, takes us on an exploratory journey to unearth the most important tool invented in the last thousand years. As he makes his case for the screw and screwdriver, he introduces a lot of great tool history and trivia. My favorite part was his discussion of the button hole, one of those very-useful but not-so-intuitive inventions.
