I have two small tool bags that I carry on each hip with an inexpensive strap. You only have the bare essentials, including a couple of gauges, a non-contact circuit tester, a 13-in-1 screwdriver, Phillips and flathead screwdrivers, a small LED flash, several markers, etc. What I was missing was a small flexible pair of pliers. Their tips work like regular pliers and the notch works like a wrench for small items like toilet/sink supply lines. They are used almost as often as my pencils and tape
