If I'm storing knives for a while, after I've oiled/waxed them I wrap them in cling wrap, put in cardboard sharp safe sleeve and then either back in brown paper they came in or sheath. Then i store them in large tupperwares. Its not much of a display but it keeps the blades and handles safe here in the Philippines as the cling wrap stops the oil/wax from drying out. I learned the hard way that putting the cardboard blade sleeves on, even when oil is applied can be disastrous in a humid environment unless you check them everyday.
