The square head robertson screw was patented in 1910 by P.L Robertson in Milton, Canada. Robertson's refusal to license his screws to any other manufacturer caused this superior design to be usurped by the phillips screw in the U.S. and the hex screw in Europe. Canadians take great pride in their robertson screws but get into trouble when they bring them abroad - as we learned last year installing an exhibition in Germany. Luckily the install crew was able to fashion a bit on the fly and we got the crates open.
I like how the Robertson company chose Columbus as their calendar poster boy; he speaks of untapped potential and constructive adventures. I hope that the ladies remember to pack a full set of bits...
