Thanks heaps for that Dave! I was thinking the one I was looking at was similar but different/smaller. It has no markings saying 'Super', but is similar enough to be an older model of this. It's going for NZ$15 (US$12ish) at the mo, when it hits a more reasonable price, I may grab it.
I take it you are referring to the Japanese Premium Screwdriver thread and the other one (links to follow - kinda late right now). I can only reiterate what you said, but I'm hoping they do fit JIS screws, since I'm planning on buying a whole set of them - will **** if they don't fit! lol
So yeah, I would like a definitive explanation... having said that, dede2897234, didn't you get a set of Vessel drivers? What did you think?
