Robertson Screw and Screwdriver

The Robertson screwdriver has a square head, so it's easy to use one-handed and the screw heads almost never strip. You can also leave the screwdriver sitting in the screw and go to get a plate of poutine and it'll still be there when you get back. Unfortunately, the one thing Canadians do better than designing great products is making awful business decisions (anyone remember the Avro Arrow? Probably not), so almost no one uses these things outside of Canada, preferring the Phillips screw or other such pičovina. Well, don't bother asking us for help when you're drowning in money, America, because we'll just laugh and throw a bunch of trees, water and cheap natural gas at you.
