I see your point, alex, and I don't disagree with that. But with a 6 point, it is harder to round bolts off, that's just my experience. In your illustration, that is the spot where a 12 point wrench would be flexing, and about to let the bolt slip by to the next set of edges. I'm not saying 6 points don't flex, I'm just saying that you have less chance of having to break out the Vice-Grips when using a 6 point.
As far as the wrench, I do vaguely remember those wrenches. Certainly not a standard line wrench. No worse than an open end wrench, eh? But no better? If not, I'm sure that's exactly why they didn't sell, and why they are not available anymore.
After just writing that, I realize that we are kinda hijacking this thread. I think the original post's questions were answered, though?
