These are the two toolbags I drive around with most of the time. They let me handle most of the general maintenance and light carpentry tasks I come across. They used to all be jammed into one bag, but it got too heavy so I split it in two. At one point I weighed the handtool bag and it was 28lbs. The other one's about the same, they make for a balanced carry.

Lefthand side is the "Drills Bag" that has battery-powered tools Usually just the two drills (drill for drilling holes, driver for driving screws,) but sometimes circular saw, jigsaw, and angle grinder as needed. I find metal bits on the jigsaw are often nicer than the angle grinder for cutting metal. Righthand is the "General Hand Tools Bag." It's made by CLC and you can find them on ebay. I chose the one with the most pockets.

"Drills Bag"

• Drill and Driver 18v battery tools, with a spare battery

• the driver has three holster slots on the tool

• double ended phillips and flathead driver

• double ended Torx T-25 and T-20 driver

• a 3/8" socket driver that matches my socket set

• drill bits (the yellow & black case) plus some masonry bits in the little blue-cap tubes

• driver bits. (the blue & red case) I put a good deal of effort into selecting and laying out this set. it includes most common sizes, plus a harbor freight security bit set that I cut to fit into a general purpose box.

• angle grinder discs and jigsaw blades, stay in there all the time.  The cutting discs often break though as the bag gets knocked round, I need some kind of case for them, or maybe the angle grinder should have its own dedicated case.

• WERA little hand screwdriver case. A recent addition I don't go to that often, but has long driver bits which can be useful, and backups of some bit sizes

• little torpedo level, because this is a kit for hanging pictures

• Construction screws (red case). 3 1'2" and down, 2 1/2" are most common, small screws are critical too. As are washers that match the heads, for occasions when you need to screw something down where the hole is larger than the screw head

• Sheet metal screws (clear case).

• Included in top picture: 18v battery Circular Saw, Jigsaw, Angle Grinder. These are only carried intermittently as needed.

I hope you put some thought into your own kits, whatever they are, whatever they're for. Tools become affordances, and the affordances you've internalized shape how you see the world.
