Well, mostly plastic. Here's a mock up version:
I keep making it smaller, but the wolf head on the shoulder still seems a little big, although it is proportional to the old model. I compared a lot of items to the old model for scale; for example, the old metal sword is as tall as Ragnar to his topknot, and the wolf-shoulder head is about the same size as Ragnar's head, so I kept both of those relative proportions.
