PB Swiss 470 Bike Tool. Goes with me on every ride.
I have a number of fine mutli-tools (some expensive); however, the only one, the
only one that can function as good as a regular tool is the PB Swiss Bike Tool (made in Switzerland). The handle's side is also a full-functioning tire lever. Not cheap but the best I have found and I have Park, Lezyne, Pedro, Crankbrothers, etc.
Amazon has them sometimes. Their US distributor has them too:
