Warning! This page contains spoilers for The Hammer of Thor.
Mallory's serrated knives are the primary weapons that Mallory Keen uses.
In chapter eighteen of the same book, Halfborn tells Mallory to shut up and she reaches for her knife, most likely to threaten the berserker.
Although not clearly stated in the beginning of The Hammer of Thor, it can be said that the knives Mallory uses to fight the lindworms at Valhalla are her serrated knives. The same can be said for the scene where Mallory helps fight the giants at the wedding.
