We've had threads dedicated to tools, to tool rolls and to a few other things tool carry-related, but I can't seem to find a thread related to tool boxes, tool bags, tool belts and other EDTC carrying "devices". I'm talking bigger tools, here, not just a precision screwdriver and a multi-tool. I usually keep a rolling tool box in the back of my vehicle, but a recent back injury has me rethinking such a large, heavy box ... and looking for creative ideas. I'd like to organize my tools like I organize the rest of my EDC - in layers: tools that I almost always need, tools used somewhat frequently and tools only used occasionally. That way, I don't have to lift the big, rolling tool box in and out of my vehicle on every job. So ... how do you carry your (bigger) hand tools like screwdriver sets, wrenches, hammers, drills, saws, drivers, etc?
