I was going to mention Robertson screws when I first saw the post, but then
I realized the Robertson head is only used for wood screws (AFAIK), so this
wouldn't be an actual "Robertson" screw, even if it came from Midland.

I don't believe that the Robertson's failure to dominate the world
wood-screw market is a patent issue.  It's just that Canadians have always
been so much quicker than others to recognize when something has intrinsic
merit.  The rest of the world have stuck with slot-head (eccchhh) or
Phillips-head screws, much to their detriment ;-)

Robertson Rules!
