I dabble in bonsai as another hobby, and this Japanese vendor came very highly recommended by folks on the bonsai boards that I frequent. Great quality tools, excellent customer service, and very fast delivery from Japan (on the order of less than a week).
While on their site, I noticed that they offer a full line of various types of tweezers. It's been hard for me to find good tweezers for modeling. I think I've bought and otherwise gone through about a dozen tweezers, and really only have one pair that seems to do it for me. So, I bought a few from that website figuring I would try them out.
Wow, the quality, feel and fit are fantastic on their tweezers. Much better than what I was trying from vendors like Micromark. A good chunk of their tweezers may larger than what we need building model ships, but they have a few shorter ones that work very nicely.
Anyway, just thought I'd pass their name along in case there are others that use tweezers a lot and have had a hard time finding good ones. I'm not affiliated with them in any way, just a very satisfied customer.
