In 1908, a Canadian fellow by the name of Peter L. Robertson came up with a better screw, commonly known (in Canada at least) as the Robertson screw. The design was superior in many ways to the slotted screw and quickly revolutionized an industry.
For one reason or another the design never left Canada until recent years and so I'm wondering... wondering if any of our members here throughout the world have heard of, or are using the Robertson screw.
