I'm gonna pipe in, being a martial artist and someone who has trained with weapons. It is literally impossible for him to have that many weapons, let alone run and jump with them. Strength aside, that much weight on his back for who knows how many hours a day would destroy his back, especially with the added weight of his armor. And I don't just mean muscles, those can be trained. I mean bones, tendons, nerves, etc. There wouldn't even be enough space for them on his back, the sheaths would get caught and tangled on one another.

Not even going into the fact that at only thirty, taking in to account the time he must have spent in the forge learning his craft, he wouldn't have the time to have learned even the basics for each weapon. Because despite the fact that most are swords, every one is used differently.

Not trying to pick on you or anything. Just stating my professional opinion.
