sword made from the iron in human blood?
As the title says, I wanna know if hypothetically this could be possible. Sword or even something smaller like a knife. How many people would you have to… y’know… and how would you even get the iron from the blood to actually turn into a weapon? Also the quality of the iron. I assume it would be very shitty quality and wouldn’t make a good weapon. But I’m still curious about the how of this situation. How would you go about it. I don’t wish to harm anyone or actually make a blood sword, but the idea sounded pretty dark and I think it would make for an interesting concept in writing.
