Lot of 8 folded Bandsaw blades. Unmarked, Unbranded. No visable markings?

I measured one of these blades and I am assuming that the rest are the same.

It is just too hard to fold them back up. They appear to be sharp. Nicks, dings, oxidation and rust. 

They may need to be cleaned. I believe they were for a vintage Powermatic bandsaw I used to have.    

Sold "AS IS", No Returns
