Tool Pouch? I carry two, one has the carhartt logo on it, one doesn't
[Linked Image from getzs.com]

I was just taught to do most things with 4 tools - Kleins, channel locks, flat head and phillips head. They all fit into those 2 nice little pouches.

This particular model of tool pouch, has a bonus pocket to carry a fluke tester.

If I can't fix it with those 5 items, then it's specialized and we go get the right tool.

Otherwise, a tool belt and pouch is just a burden.
