Name for magic sword?

Hi, guys!

Thank you for your creative, magical, and beautiful names for the magical foxes in my story!

But in the same story, there's also a human woman named 'Amanda.' And she has a sword.

This sword can float or fly and obeys Amanda's commands. But it still needs a name that does not appear in any other story.

I look forward to your great answers.

PS: The look is a Pinterest pin, but roughly this is what the sword is supposed to look like.
