I found about the best combination toolchest/bitz box a while back
The top section is nice and open with lots of room for tools, and it has a recessed area on the sides with holes cut for long tools like scissors and razor saws. Only problem is because of those holes it's not good to have small tools (like your pin vice or exactos) rattling around loose in there, but there's plenty of room for a smaller box for those fiddly bits if you want. I've got room for my bigass knife kit, two sets of files, the tin I keep my small tools in (a couple exactos, my drill bits, paperclips for pinning, pinvice, reamer bits, some spare magnets, my 6" straightedge/depth gague, etc),, nippers, wire cutters, pliers, my plastic cutter, scissors, saw, reamer, my smallass knife kit, tube of GS, tape dispenser, a bundle of plastic strips and tubing, glue, guitar strings, etc and still have room around inside the top compartment for some more crap if I can think of anything else I need.
Then there's the front bit that flips down with three removable compartmentalized boxes. I was able to consolidate several small bits boxes and one big one into two of these boxes, with one spare. The only problem is there's not as many dividers as I would like, but if you have plasticard you can make dividers.
With a little padding it would make a good miniature transporter too. The compartments are deep enough to stand a normal marine up inside and the top os suitable for vehicle parking
