Although it's the type of tool designed for working on bikes, this carry-along pocket ratchet would make a great addition to any EDC toolkit. It's super small and lightweight, and both the ratchet mechanism in the head and the opening at the end of the handle accept standard ¼" hex bits, making it the ideal tool for all those little screwdriving and wrench jobs that aren't worth breaking out a bigger kit for.

The ratchet comes with a separate extension bar that doubles as a T-handle when needed, so either way you use this tool, you always have the leverage you need.
