> And I still don’t know what the Sampo is!

No one does. Sampo is basically just a magical MacGuffin that brings wealth to whoever has it. In Kalevala it is usually understood as a mill that creates infinite grain, salt and money, but different folk stories have different interpretations.

Don Rosa wrote a Kalevala-based Scrooge McDuck story (The Quest for Kalevala), and a "mill that creates infinite grain, salt and money" (gold) is of course an ideal object of desire for ol' Scrooge.
