W-well, I've been working on this hammer. In the forge? Anyway. I've kind of...hit a road block. We didn't exactly have a lot of kinds of metal on Berk, and well, the point is: I want to make it light enough that I can...you know, actually use it. In case Iiiii actually have to...fight. At some point.

So what I'm getting at is: do you have any ideas for a kind of metal that's light but still, you know, strong?
