I can't go into a hardware store without looking through the tools and wondering what they are for.  And I wonder how people long ago used tools and what they looked like.  This book shows us the history of 20 tools invented as long ago as 2.5 million years.  From sticks and stones to power tools, take a quick look at the history of tools.
