How do you think they kepted them imprisoned for so long. Also it was the Aesir who made the chains and cages that kepted Fenrir, Loki, Hel, Nidhogg and the others imprisoned, not us. Also there is no longer anyone alive skilled enough to craft such devices.

no maid 'til bedded; no ice 'til crossed;
no ale 'til drunk."
