Lots of good ideas here, I will use several. I do wonder what he intends to do with it, there are two knives in the case (and I would hope at least one in his pocket) as well as a razor blade and several other cutting tools. When space is short, duplication is not always a good thing.

In general, I think the purpose was to show that you can have a functional basic kit that could easily fit into the glove compartment or similarly small spaces if you do not have a full-blown toolbox in the trunk - maybe. The duplication issue is a good question.
As a further question: What, besides glues of various sorts, would you carry in the straw ampoules?
