Personally, I don't think Nozarashi was ever in a semi-released state. When Kenpachi said his blade was always released, that wasn't actually the case. I believe that he "thought" that his zanpakuto was in it's final stage, while it was actually just in it's sealed form. This was because Kenpachi never tried to learn his zanpakuto's name. Even when he wanted to learn it's name, he couldn't because he restricted his powers. So its always been in it's sealed state. Even if you use Ichigo's Zangetsu being constantly released, I also have a thought on that. The reason why Ichigo always had Zangetsu released is because of his inability to control his spiritual pressure. Or maybe he likes it that way. It's not like other captain's zanpakutos where they would be a huge inconvenience.

As for Nozarashi's ability, I doubt it has any. It might just be a giant axe to increase Kenpachi's destructive power.
