It only took you guys 100 years to catch on to the "Robertson" screw and
driver (you guys call them square drive). I guess it will only be

The Robertson Screw Driver was invented in 1908 and has been well used

Robertson Screw driver was invented 10 miles down the road from me. They
named a school after him and the Robertson Corporation is still around in
Milton.

before the Canuck version, in New York City. Robertson's screw worked
because he figured out a good manufacturing process. The American screw
head was a failure and that's why the Yanks used Phillips
