And they're called Robertson drives.

That is genuinely interesting, thanks :-+ (I am adding this bit in brackets to assure you this is not sarcasm as it is easy to be misunderstood in situations like this.)
So a square drive key is called a Robertson and was manufactured by the same as although Allen may have previously come up with the idea, could not make it feasible to produce.
So:
Square drive key = Robertson
Hex drive key = Allen
Correct?

Yep correct, yet if you speak of Hex or Square drive everyone instantly knows what you're talking about. :)

My thoughts exactly. Which is what frustrated me in the first place when reading Hex, Allen and squarish in the same definition.
I don't know much about electronics but if you saw a wave on a scope that was supposed to be a square wave, would it be ok if the corners were wobbly? Would it be ok if they were squarish? Or would it mean something was not right and need addressing?

Aha! I see lots of squarish waves. :)
I will continue reading though I think it will be a while before I understand it all.
Thanks
