I keep a similar kit of tools. However I still had problems fitting _everything_ i typically need in a small case. Typically I'd have to decide if I needed more socket or driver options and add/remove tools to accommodate.

I have since solved this problem: 1) Tool-Check PLUS from Wera: fantastic and highly condensed set of sockets, bits, ratchet and driver. all high quality. 2) Leatherman ARC: replaced a more basic multi-tool. I like the high quality blade material and the whole thing is very durable, i can squeeze and crank the pliers without worry.

The leatherman is a bit of a splurge but I highly recommend the tool-check for tool-using EDC minded folks. They make good gifts too.
