Looks like I should have gotten a multi-tool without the chain tool attachment, and a separate chain breaker. Oh well, it didn't cost much. I also just checked if my 90-degree needle nose will work, since I have a KMC with missing link on the bike now (which was apparently OEM) -- it won't work, since it won't fit into the links that have inside plates, as it needs to. So I'll get the missing link pliers, too. My wife's bike chain is close to needed replacement, too, so I'll put these new tools to use right away, and be ready for next time.

I'm going to go with the KMC X10SL, even though it's a bit pricier. And I'll get the KMC X9SL for the wife. For a chain breaker, do you recommend the Topeak or the Oumers Universal Tool?
