Sai tilted his head slightly in thought as Usopp began discussing his idea. His eyebrows furrowed. "So basically what you're saying is that you want to help provide weapon making services for anyone who's willing to make do with whatever they can get their hands on - not necessarily a sword," he said bluntly. It wasn't a bad plan, all things considered. It would help to equip others. But there were definitely drawbacks as well.

"Where would that leave you, though? You'd spend your nights making weapons for others and not for yourself. Won't your companions want you to come with them, or will they be staying to help you as well?" Unless the pirate planned on charging, there was a good chance he wouldn't even get much back in return for his services.
