I'm partial to stuffing the blade and hilt into two separate pool noodles and then cramming the lot into a tripod case or dufflebag, lol.
Lol, pool noodles, I am preferable to the pure functionality of the concept... currently I've always got a towel and a backup to wrap my hilts in so they don't bump too much. Then yeah the good ole stuff them in a bag approach hasn't failed yet, but I'm desirous of an upgrade.
