Uh . . . you quote F/Z, which is good, but then you mention Authority, which doesn't actually exist as a concept in the Nasuverse?
That's something that Murder and Nameless made up to skip having to explain conceptual strength and age and legendary notability and stuff in Fate/Black Reflection.
As for mini-blades . . . well, no, they don't work like that. It's more like jagged, two-inch metal teeth that interlock to protect Shirou's squishy parts. It's nothing as pretty as little Kanshou and Bakuya-patterned tiles or whatever.
