This should have been figured out a long time ago. The Vikings were in many ways desperate people. They didn't let the womenfolk so some of the jobs for menfolk because they were progressive liberals, they lived in such a way that no able hand could be wasted. Strong enough to carry an axe? Great. We're getting attacked by our neighbors, and there's X of them and Y of us. Grab a damn axe.
So yeah, of course the shit they made had a practical purpose to them aside from looking badass; almost all the stuff they had that was considered strictly ornamental they bought from folk like the Arabs or outright stole from others.
