But since aiki comes from kenjutsu originally, how does that work sword-against-sword? And how does it explain aikinage?
If you are referring to the "aiki" in aikido as coming from kenjutsu ... I don't know that it did. It's something that I think people are researching and finding that maybe there wasn't a whole lot of kenjutsu in aikido's history. Dunno. Better people than me are talking about it on E-Budo.
