I do commercial and industrial, I have a small bag, 6in1, 4in1 nutdriver, my Fluke, 6in crescent, needlnose, a med. sized set of dogs and a rope. I can do almost anything with that.
What amazes me is how many little things...and some big things that accumulate at the bottom of my bag...tape wirenuts stakeons pneumatic brass screws self tappers... I think that stuff weighs more than my tools.
My most used tool is my Fluke. Wouldnt be alive today without it.
