Good evening all,
In continuing my reading and review of the usual sites we all undoubtedly frequent, I came across this piece on Aoi that raised a lot of questions in my mind relating to how the NBTHK categorizes things:

Photo of the origami and juyo setsumei attached as well.
So, as one can see the blade is currently in wakizashi koshirae. However, it has been categorized as a naginata, not a naginata-naoshi. If my Japanese is correct, the juyo setsumei indicates that the nakago is ubu, but also that it is cut down ("生ぶ、先を切り詰める"). The original mei remains. The kissaki has a kaeri and so as far as I understand it hasn't been reshaped.
Questions I have for the members of the forum:
1) As this is now in wakizashi koshirae, with nakago modified to make that happen, why is this not a naginata-naoshi? Is this because the kissaki hasn't been reshaped?
2) What makes a nakago ubu? In this case, it has been cut down, and so it isn't unaltered. But I assume it hasn't been moved up the blade (though I've also seen blades with machiokuri listed as ubu).
I appreciate all of this likely is me simply trying to be a bit more fixed in categories than is helpful. But the blade, fittings, and paperwork just stuck in my brain in odd ways, and thought it might make a good set of learning points for me.
Any insight anyone can provide would be greatly appreciated!
