there was never a line indicating a broken promise for using it. like sorry but i gotta use this type of thing.

I could be mistaken, but wasn't that about the Rasenshuriken because it damaged his arm?

And I thought they were referring to his still incomplete Rasenshuriken. He did say he still hasn't perfected the technique, correct?

you are mistaken
those pages are right before the mission to save gaara, the rasenshuriken was developed after chakra natures were introduced.
