We still have no confirmation how exactly a blade is turned black but it's probably through CoC infusion.
By this logic any sword that you infuse/coat with CoC will turn black, as Mihawk stated, every blade can become a black blade. How this is supposed to exclude supreme grade blades beats me.

While, honestly, I have a hard time wrapping my mind around how the blade ranking system even works and what decides which rank a sword has.
