Brok gave the hammer to Thor. That is the way Thor got his wonderful
hammer.
Then Brok said to Loki, "You said I could have your head if my things
were the best."
And Loki was angry and said, "Yes, I told you that you could have my
head. But you can't touch my neck."
Of course, Brok could not get his head without touching his neck.
So Brok did not get Loki's head.
