Larger knife collection storage

Hello, I have a growing collection of knives and im curious what others are doing for storage. Collection is between 200-300 knives, predominantly vintage slipjoints. They can’t be piled up at all due to their value. Right now i have them in two multi-drawer machinist’s chests but i am not sure if there is something even better others are using. For anything of lower value or “user” knives I have plenty of options or for small display cases but this is a fairly substantial collection that all need to be handed well.
