If I were to let my imagination run wild, I would try to hollow out the scales to allow for needle(s) and thread. Also, I would replace the corkscrew and eyeglass screwdriver insert with a flint and striker combination. The striker could still be unscrewed from the flint, which would be hollow. Personally, I like replacing the toothpick and usless tweezers with an LED and a retractable pen, and would do so here.
