This book is composed of equal parts (1) why the author chose the screwdriver as the tool of the millennium for his article in the Sunday New York Times Magazine (2) where you have to go to find out about screwdrivers from the past (3) how he developed the information for this history of the screwdriver and screws and (4) the geniuses who developed the key advances in the technology of these useful devices. The style is a bit rambling, much like what would happen if you were chatting about the subject over a barbecue in the back yard with plenty of time on your hands. I can assure you this must be the most complete and authoritative book about screwdrivers and screws ever, especially since the author points out the virtual absence of any prior material turning up in his research.

Let me summarize the key areas. He picked the screwdriver as the tool of the millennium not because he thought of it, but because his wife told him that it was the one tool that she always kept around. After having gone through his own tool kit, he had not even thought of the screwdriver.

The first place where much shows up on the screwdriver in older texts is Diderot's Encyclopedia. In those days screwdrivers were called turnscrews.

To get a flavor of the screwdriver in the middle ages, when it seems to have appeared, you have to look into armor and early guns.

The screw goes back much further, showing up in useful form for Archimedes in Greek times as a way to raise water.

Screws later played many other important roles, especially in presses (including, of course, printing presses).

Lathes turned out (pun intended) to be an important related technology for making screws precise and consistent.

I learned about some interesting related technologies, including Greek mechanical devices with gears for calculating the orbits of heavenly bodies.

Then, we finally get down to gears and the development of improved lathes and the Robertson and Phillips screw heads. He prefers the Robertson (which I had never heard of before) which uses a socket top to screw in and remove screws.

At the end is a nice set of illustrations along with a glossary of tools.

This book is probably going to be a classic Father's Day gift for decades, along with a Robertson screwdriver, socket set, and screws.

Overcome your misconception that you know all you need to know about screwdrivers. You'll be pleasantly surprised by this gentle and unassuming book.

When you are done, pick something else you think you probably know enough about and search around to find a good book on that topic as well to expand your own knowledge further. Keep doing that, and some wonderful learning awaits you!
