I wouldn't say I specialize but I've done it before. I mean, I can fix weapons systems pretty well, but I've only ever actually built one gun. It's a really great gun, though.

I don't know if I would be a really great teacher, either. One time my friend Gai asked me about the ship's propulsion systems, and even though he seemed to enjoy hearing me talk about it, he didn't really learn anything. In fact, he tried to stick his hand into something super dangerous about a second after I told him about how dangerous it was.
