What did Thanos do to Eitri's hands? Are they:
encased in metal?
cut off and replaced (by Eitri or Thanos) with metal?
turned to metal?
In Avengers: Infinity War, Eitri reports on Thanos' visit:
Eitri: I thought if I did what he asked, they'd be safe. I made what he wanted. A device capable of harnessing the power of the stones. And he... and he killed everyone anyway. All except me. "Your life is yours," he said. "But your hands. Your hands are mine alone."
I'd assumed that Thanos had somehow removed Eitri's hands and taken them with him, and that Eitri himself had sourced a metal replacement (I'd subconsciously assumed that prosthetic limbs were ready and waiting or else easily made). Now I'm thinking that Thanos has opted for an easier storage solution and simply encased the hands in metal or used some of the infinity stones to turn them to metal. Is there anything in universe that clarifies this? MCU answers preferred, but comics also an option as this is pretty specific.
Inspired by the answers to this question.
