Trucky,
Only applies to flat-tip blades and how you described the profile is correct. PB Baumann/Swiss was, IFAIK, the first to come up with that, and it's their standard profile. But it's also available (or was available) from Wera and Witte/Stahlwille. Perhaps I'm missing other brands.
Cosmik,
Thanks for the interesting photos. I enjoy looking at them....except for the ones that are blurry.

...and nice selection of brands.
Cool, a set of Handy-Endy sockets! I'm wondering if the Handy-Endy was for export only; I've never heard it mentioned in Japan.
Cantause, yes, I was wondering about him. He hasn't been here in a looong time. Must be busy in school like you said. Hope he's alright.
Of all the major European tool brands discussed in this thread, I think USAG has the least amount of coverage. Are they just not widely available? USAG is/was a huge name in Formula 1. I think there once was a time when USAG was THE dominant choice for teams. Of course, Beta was another one.
