Skeletool® 7-in-1 Multi-Tool | Leatherman​​

At a mere five ounces, the Leatherman Skeletool has a stainless steel combo blade, pliers, bit driver, removable pocket clip and carabineer/bottle opener.

I have two, a Micra that I keep in a pocket and a Free P2 that I keep in an EDC kit. The Free P2 was a bit heavy for my pocket and the Micra provides what I need 99% of the time. Still, the Free P2 or similar has some tools where when you need it, you need it.
