Re: Iaito and bokkens @ Airport customs
I have been using a hardshell rifle case as well but have not done any traveling with my swords for a few years. My Sensei however uses a hardshell golf bag. He gives them to the porter and is never questioned about them, everyone just assumes they are golf clubs. Be prepared though to explain what they are in the event they question you but in general you shouldn't have to tell a lot of people.
