I'm not surprised that Yhwach's sword had a name - after all, even Uryu has Ginrei Kojaku - I'm just surprised that it served any purpose for a Quincy's weapon. Can't they just Green Lantern things up out of reishi all they want, and so Yhwach could just materialize a new sword that isn't affected by Ichimonji? I can't think of any significance of a named spirit weapon other than sentimentality.
