O2 isn't commonly used for blades over here but it will serve the purpose. As far as I can tell it is normally sold in an annealed state. Why do you think yours is hardened?
Anyway, if you are certain it is already hardened then you may as well send it back considering your lack of tools to deal with it. That begs the question though of how do you intend to harden it if it was annealed? Pretty much requires the same tools ....
