It does seem like the dagger would have been made recently by Ochi, doesn’t it? It may be easier to find one moment to state that somewhere rather than change several moments to make the blade seem older.
If the blade was made, say, fifteen years ago, then it would even make sense to keep the goonies moment in.
But why would he create a dagger with a shape resembling the death star wreck?
So we can have a Goonies moment. I’m sure it was a visual JJ realized would be cool regardless of logic.
