Uhh... More. Lol.
I love the tool analogy, my buddies are always shocked by all the speciality tools I have (torx: inverted, "tamperproof": all the Allen's, flare wrenches, 4way wrenchs, manufacture specific tools, 4wd hub sockets, hub removal tools, etc,). Why do I have all these tools? Not because I really, really have to have them to get my job done. But, on rare occasion, these tools are necessary.
