Maple wolf R.G asked Rick Riordan:

Where did Nico get his iconic Stygian Iron sword, and what would happen if he accidentally cut himself with it? Would his soul get sucked in? That would be unsettling. And is the Nico di Angelo adventure series going to be a trilogy, or is Court of the Dead the last book? (BTW, I love Solangelo, and I've read TSATS so many times that I can recall it scene to scene. Thank you for creating Will Solace. Nico needed him.)

Rick Riordan There is no canon on that in the books, as far as I can recall. I imagine that Stygian iron is mined from the banks of the Styx, probably by undead blacksmiths in Hades' employ. No, the sword wouldn't affect Nico if he cut himself, other than getting a regular cut, which would still hurt.
