Heritage Minute #6: Robertson Screwdriver

Peter Lymburner Robertson was a Canadian inventor born in 1879 who invented the Robertson Screwdriver. He was born in Seneca Township in Haldimand County. As a salesman for a Philadelphia tool company in eastern Canadian, he was demonstrating tools one day when his straight-bladed screwdriver slipped and cut his hand. This prompted him to design a different drive for screws that would slip less, leading to his square-socket drive. The Fisher Body company, which made the car bodies for the Ford Motor Company, was one of Robertson's first customers and used over 700 Robertson screws in its Model T car. Henry Ford, after finding that the screw saved him about 2 hours of work for each car, attempted to get an exclusive licence for the use and manufacture the Robertson screw in the US. He was turned down by Robertson who felt it was not in his best interest and shortly after that, Ford found that Henry F. Phillips had invented another kind of socket screw and had no such reservations. Robertson headed the Robertson Screw Company until his death in 1951.
