KC, consider getting a really good quality multi tool, Mine has a chain breaker and its what I use to size chains when I put on new ones, and it works great.
I have a couple of old crappy ones that have busted pins or whatever and cant use them anymore but my Lezyne multi tool chain tool works wonderfully.
I know you are looking into touring, and I highly recommend getting a lezyne or other good quality multitool that has one in it. yes, they are more expensive than cheap multitools, but totally worth it, and small and compact.

I dont recall whtich one I have, but they all appear to have the same chain tool.

and a good multitool is worth it in the long run anyway.
