On my touring bike I carry a couple of FiberFix spokes, then I don't need a tool to remove the rear cluster with.
I keep my bikes up pretty good, I haven't had a breakdown for a very long time, maybe 25 years ago. I wasn't watching where I was going closely enough and hit a stick that was sticking out, my front wheel hit it and broke a spoke on a 36 spoke rim, the rim had just a slight wobble, I adjusted it back to like new and rode home. That was the first time and the last time I had to use a spoke tool while on the road.
