Ever seen this set of SO screwdrivers?

I'm thinking there probably are not too many of these out there. I also have some of the Buick Know How stuff that is made by Snap On.

I've seen a set. I've got them in the other room.

Not sure how rare they are, my set is the only set I've seen but I've never actually used them. They must have been the best option at the time though.
