How many times can you fold a katana?

Now, I've heard of people bending steel swords for demonstrations, but folding a katana? That's an interesting concept. So, let me get this straight - are we talking about physically folding the blade of a katana, like you would a paper or a cloth? Because if that's the case, I must say, I'm skeptical. Katanas are renowned for their durability and rigidity, made from high-quality steel that's been tempered and folded multiple times during the forging process. But to actually fold the finished blade? That seems almost impossible. So, let's assume we're talking about a theoretical scenario where you could somehow manipulate the steel to fold it. How many times could you potentially do this? It's a difficult question to answer definitively without knowing the specific material properties and dimensions of the katana. However, given the strength and hardness of the steel, I would venture to guess that you wouldn't be able to fold it more than once or twice, if at all, without causing significant damage to the blade. But again, this is purely speculative. In reality, attempting to fold a katana would be a fool's errand, as it would likely result in the destruction of the blade. So, to answer your question as best I can: theoretically, maybe once or twice, but practically, never.
