If you’ve got the very small leatherman pliers then it’s a squirt, the next size up is the juice. Both ranges now discontinued sadly. Have both types, plus a few others like a Wave, mini tool and skeletool.
I’ve had a toolkit refresh. As part of that I picked up a Topeak ratchet rocket lite dx+ which really does work very well, and paired that with a Leatherman Bond. It’s slightly heavier than the skeletool but lighter than my juice (although that was the bigger XE6 version)
Topeak ratchet rocket dx+ is about the same weight as my Crank Brother M19.
The problem with the leatherman bit kit (which I also have), is the bits are too small to be able to tighten something up properly (like the 6mm bit), and it’s too long to fit into narrow spaces. I had that problem recently with my M19, hence why I picked up the ratchet rocket. It was the lightest, smallest bit driver socket style ratchet I could find that was nicely organised. Other options from Wera, Bosch and Silca, among others, but they also don’t have chain breakers.
