Does anyone think Annabeth's knife might be really special? I mean, it was said to protect whoever wields it, according to Halcyon, so it might be enchanted, or previously owned by some important guy/girl in Greek mythology. Maybe when some powerful enemy meets Annabeth in Tartarus, he'll be like, "that knife...the knife of (important guy/girl)! Blah, blah blah, etc., etc."
