I was not aware of the history of the Robertson head screw design. Very interesting. List of screw drives - Wikipedia, the free encyclopedia

I don't think it's as common in the US as it is here in Canada. They work great though. Lots of torque and no slippage.

I think an old mobile home I used to own, used either the Robertson head or a similar design in their construction. As you say no head slippage or busted knuckles.
