He does also seem to already be able to use his reiatsu in this way already so that is why I think it is something like this but in saying this his "kendo" kind of reminds me of air type attacks...

I think it might be vibrations because the vibrations could increase the sword's cutting edge.

The best guess that I have would be a sound/air style bankai with a chaotic overtone and mostly if not all melee style attacks
