Oubliette versus Omnium Gatherum versus Kitchen Drawer

I have a drawer, a kitchen drawer, in which are stored all utensils of imperfect categorical defintion:

e.g. knives are in the "knife drawer", but "box cutters" are in the kitchen drawer.

I have a desk drawer, into which all tedious correspondences are thrust into oblivion: oubliette.

I have a drawer of treasures, wherein my agates and steelies molder unused, side by side with holy cards of people gone from view, interleaved with intaglio business cards of mystery businesses;  a drawer of my life-history like Pythagoras' fifth element which holds all other elements; a good shepherd drawer where there is a great in-gathering:

omnium gatherum.
