I don't carry chain tools for two-day trips. The risk just doesn't justify it.
+1. Over fifty years here of single speed thrashing on BMX, clunkers and cruisers. Never broke a chain. No failure of any kind actually. Not even close. They just go in simple circles, never have to move (get abused) from one cog to another, and are exposed to very low torque forces. I don't even carry a spare master link.
