Are these vintage blades any good?

Some guy is selling these blades, but I haven't seen them before and I was wondering if anyone has tried any of them or knows anything about them.
The first blades are made in Sweden, the second in Germany and only God knows about the third ones.

Extra Tunt! Everyone needs more tunt in their lives!

They look like they are all carbon to me. Not worth using, only for display.

The Swedish ones from the first picture are stainless and probably the best of the bunch, but yeah, I guess these blades are more suited for display rather than being used.
