How can a druid keep ahold of an item while using wild shape?

In the interest of making a bouncing ooze (via Cave Druid) that utilizes Leaper’s Libation and a level of Black Powder Vaulter to jump around everywhere, I wanted to use an Akitonian Blade (tiny-sized) in order to boost my acrobatics checks for obvious reasons.

However, I have a set of problems that come with it:

  1. Oozes have no hands. (Solved via Arms of the Marilith)
  2. When I wild shape into an ooze, the blade merges into me, preventing me from obtaining it’s bonuss since I’m not wielding it anymore.

Given that I don’t want to waste actions dropping the Arms of the Marilith, picking them up, and re-equipping them every combat, how can I keep ahold of them while wild shaping?
