Grettir - Kicks shield

In front of him he held a shield with an iron rim, and acted menacingly.

(...)

He began to bellow loudly and to bite the edge of his shield, putting the shield in his mouth and grinning over the rim and getting enraged. Grettir dashed out into the field, and when he came right up to the berserker's horse he kicked the bottom of the shield so hard that the shield went right up into the man's mouth so that the jaw fell down from his chest.
