One Good Turn is a terrific book on the history of the screwdriver.

I recall details from one chapter which dealt with the Canadian contribution to the world of screws:

Robertson was an inventor and Henry Ford wanted his square-socket screw, but he demanded that Robertson loosen the fit so that Ford's assembly line workers could ream them into place more quickly.

Robertson refused to compromise, and further ensured that the screws would never be licenced for use in the United States.

A guy named Philips was more agreeable to Ford's demands and loosened the fit on his cross-hatched product, thus creating that characteristic BBBRRRAAAAATTTT! sound, the mating call of the American handyman.

I think contributors to this forum will enjoy this little, expensive book. There are lots of reviews of it on Amazon.com.

No doubt that the Robertson head is the way to go for the everyday handyman. I have a neighbour who is a licenced aircraft mechanic (engine rebuilder and air frames, etc) and I once asked him about the Robertson head. He told me that pretty much ALL screwheads on aircraft are Phillips, and not Robertson. Even though they are definitely more difficult to grab with your driver, they are apparently MUCH stronger than the Roberson because of a much smaller amount of metal removed from the screw head. Robertsons just are not used where safety and strength are needed. Interesting story anyways although I have cursed those blessed Phillip heads many times when taking apart engine cases on motorcycle engines, but at least I know why they use them.

Tap the heads sideways with a punch before attempting to undo. No problem then at all. Try it and come back with the results. No good with countersunk heads though!
