    This. The best way to stop a contamination from ruining your material, if you have no way to purify the material in bulk, is to spread the contamination to the entire material, so that it does not become a singular point of failure. Plus, by folding a thousand times, you increase the possibility of accidentally forcing nodes of contamination to the material’s surface, allowing it to burn off in the forging process.

      Correct me if I’m wrong, but I’m pretty sure they are folded about 10ish times. With 10 folds you get 1024 layers of metal in the blade. Folding it a thousand times would require an intense amount of labor, and much of the metal you be lost to oxidation during forging.

        Nah, you’re not far off. Though even with only 10 folding actions, combined with drawing out your material, will still homogenise the material, something critical if you have iron from a blooming furnace and trash grade ore.
