Hello Everyone,
I'm reporting that I finally mailed my blade to Japan for restoration with Kunitaro-san. I took Brian's advise and just went to another post office. I listed on the declaration form Japanese Antique Nihonto like Derek suggested but the person at the counter said I needed to be more specific. I was thinking to my self oh boy here we go again. So I proceeded to say a tanto and the person said again what is a tanto? And I finally replied it's a Antique sword, blade or dagger what ever you would like to call it, even a knife and they said to me, no problem. And that was that. I do believe that people make this stuff up as they go along.
I guess I should have asked to speak with the supervisor at the first Post office but then again the who knows what that person would have told to me. In the end you can ship a sword, wakizashi and tanto to Japan through the Post office with no problem what so ever.
Thank you to everyone for the advice.
Andy
