I have an old chest I picked up at a flea market, very much like the Gerstner chests that A G Russell sells. Fixed blades go in the three full-width bottom drawers laying on some felt-like material out of their sheaths. Folders and accessories go in the 6 half-width top drawers. Spare .45 & .38 ammo, paracord, CR123 batteries, and a few other things go in the top section under the lid.
Never had an issue with corrosion on non-SS, no marks on the blades because of the soft material, and the whole thing can be easily picked up and moved if necessary.
