That's right, I've decided to carry a single bits holder after a while, as only one of them fits into the inner stretch pocket of the holster and after figuring the less useful bits. If it will be siting just beside the tool - there is a good chance to loose it while unholestering the tool blindly in a hurry. But definitely that could be fixed adding a small lanyard to it.

By the way, the steel wire is a great resource for tools improvisation with LM as well. I've been making tiny screwdrivers (flat, hex) out of it, used it for shimming metric hexes (to undo them with imperial hexes), made slotted / "dimpled" nuts keys, used it to improvise nails, rivets, etc.
