I'm sure it is not the same. Cold hammering means imho (!) the improving of the cutting edge of a finished bronze sword to increase the cutting performance. This work will be done either without or just a tiny bit of deformation.

It is absolutely impossible to forge cold iron. One can hammering the steel until it is hot, but one cannot forge steel at room temperature! Otherwise one would destroy the crystalline structure of the steel or iron.

One can cut a blade like structure from a meteroid, grinding and cold hammering the edge a little bit. But this have nothing to do with forging!
