I was wondering if anyone can recommend a good carrying case for one's sword that can be checked through at an airport? For last year's seminar (when I purchased my sword) I got a cardboard box long enough to accomodate the sword, and it worked, but it was bulky and hard to carry through the airport, and not as crush-proof as I would like. Can anyone recommend somewhere that a hard-sided sword case with a carrying strap might be purchased? Or is there some other alternative I haven't thought of?
Thank you in advance!
