My toolbox is ordered in a top down methodology.
Up the top there is a code reader and multi-tester and other touchy feely tools and equipment.
Next draws down an assortment of small screw drivers torx wrenches and allen keys,
below that, 14" drive socket set and assorted adapters and small adjustable wrenches, and bigger screw drivers.
Next draw down 3/8 drive socket set and 6 and 8 inch adjustable wrences, pliers and the like.
Next draw down, open end and ring spanners, 1/2 inch drive socket set and breaker bars, 10 to 16 inch adjustable wrenches
Next draw down, Hacksaw, chisels,snips, side cutters, end cutters, prying and breaking tools, hammers, vice grips etc.
At the bottom, a cabinet with 4 and 5 inch angle grinders and consumables, crow bars, and hammers of thuggery.
At the side of my toolbox is a trolley jack and four axle stands, because if Ive exhausted the draws and the cabinet below, and it still doesn't work. Then it doesn't need any wheels does it ?...

On the other side of the toolbox is a fridge with beers in it, satisfyingly an accurate gauge as to how the job went.
