After fiddling around with a multi-tool chain breaker today (rear derailleur problem on trail!) I was wondering if there was a tool less awkward and fiddly?
Is the KMC tool any easier to use by cack handed folk with too many thumbs?

Tbh I find multi tools rubbish at tooling.
They are quite often heavier than just carrying an actual chain breaker and the exact hex keys you use or a mini ratchet.
Sorry no help to you at all.
Some multi tools have quite decent chain breakers, some are a bit meh. My Lezyne multitool has never failed me.
The chain tool on my Topeak Hexus works well - has been mentioned by others on here too.
Also the Park Tool mini chain breaker CT5 is good as a standalone portable tool.
Have used both 'in the field' and can vouch for them.
Which chain breaker didn't work for you? My Park Tools CT5 is the one I use in my workshop! I do also have a cheaper one which to be honest is pretty similar. Both are pretty light but not as light or compact as the more typically portably ones that come with multitools or sets designed to be carried
When I was out in Spain, I snapped a chain and man we struggled with 2 multitool chain breakers - had to use a rock for leverage in the end. I've bought the fella who guided me one of these -

It was the nearest I could find to the old Park CT6.2 folding one, which I have and works great.

I have this one, but I have ditched all the gubbins and just use the head and pin/screw thing as the rest fits allen keys and spanners already in my on bike tool kit. Its very strong and never failed me. The head is very small and takes up little room.
The next best one (much as I hate to say it) is the park tool CT5, its compact, light and strong.

i used to carry a kool tool for chain breaking, worked really well.
That said, with quicklinks, why not just open the chain at the link (if you need to take it off for some reason) and a spare link for fixing it again? might not cover every single scenario but would cover most.
I have bought one of those KMC ones for my road bike as it weighs 26g or something equally ridiculous, but not used it yet. I must experiment with an old chain...
