Since most of them use magic, I am less sure that many would feel the need to have weapons to begin with. Rubato-senpai is a hunter though. I have seen him make his own arrows. But... I suppose since he uses a bow, he would have less reason to make things like bullets to begin with.

[Hmm...]

Certainly, I know that I would not go anywhere near a forge. If I were to burn myself, it would be devastating for my career.
