I finally got around to replacing my bike's cassette, and towards that end (and expecting to replace various other consumables in the future) I decided to shell out for a Rose All2gether toolkit:

I'm puzzled by what exactly some of the tools in the kit are, namely: the big wrench below the chain whip, the thing in the upper right corner, the truncated triangle below the cassette tools, and the thing next to it. Also, the small wrench opposite to the chain tool has a 90 degree protrusion at each end.

Here's a close-up of the smaller mystery tools:

The triangular one has channels running through the other side from the corners to the opposite edge, with a circular depression machined out of the other side.
