Some great ideas, but what if you get a power cut?
When I worked on the sites all that fancy gear knocking about would last about 10 minutes before it was "Whizzed". We only ever took the basics and that is all you where covered for by your companies insurance. Beside that not many sites had any sort of electric on them, you hand balled nearly everything.
Today of course its far easier and quicker with cordless stuff.
I suppose the main tools are a good 18 volt ion combo cordless, sds mains cable all the bits to go with them. A circular saw if your taking up your own floors with a good quality fine cutting blade, not a rip blade that turns a floor into firewood. I would also say a roto tool. You could go on and on depending on the work your doing.
Mostly though you can get by with a good medium slot head screwdriver and a No 2 Posi driver, plus a couple of Conex type spanners and a crows foot. With of course our old mates, a pair of medium size Footprints, large and small hacksaws. Primus blow lamp, pipe cutters and file. Hammer and chisel, pliers.
It all depends what your work is. You can't dress lead with a screwdriver and you can't solder a joint with a lead dresser. I wound up over the years with tools I seldom use, bought for specific jobs, but if I worked on similar jobs again, I would have to go and buy again.
The rest of the kit are tools of personal choice and add on's.
