The story goes that Mr Robertson licenced the manufacture of his invention to a French firm who tried to drive him out of business. He regained ownership of the devise but then got gun shy of others so refused to licence it again to his folly. Too bad, it beats the heck out of most other drive patterns for general usage. http://www.mysteriesofcanada.com/Ontario/robertson_screws.htm




Sounds like he was paranoid... I wonder what caused that
