    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.
