I would also add a question. Are we talking bare minimum in terms of size, weight, or functionality?

For instance, many here would consider the Photon to be a minimum lighting standard, but I can't see with it unless my environment is pitchblack. As soon as dusk sets in I have a flashlight at the ready.

My own personal lighting EDC minimums are the Inova X5T for LED and the SureFire E2e for incandescent. I am never without them, even in my dress suit. It takes a bit of doing, but I manage to cram them in!

Many here don't leave home without the Wave. I too, carry it in my briefcase, but not on my person. I carry my MiniChamp and any one of my small locking folders in my pockets. There's not much I need to open in suburbia that the MiniChamp can't handle. On the other hand, should I need to break down one of those huge heavy-duty cardboard boxes, the Wave's blade would come in handy.
