Which durable Chain Breaker? I bought the cheapest chain breaker, XLC 10EUR, and its head got loose on the first try (maybe due to my poor handling or it is not well-done product). I was on the journey and had to get it so did not have time to investigate for better long-term option. This reply raised the issue again, here. The shop-keeper said that he used some very expensive tool because it "is much better in everything but for great price tag". Which durable chain breaker would you suggest to replace XLC? And if you have tips not to break it, please, do not hesitate to contain.

I use a park tool breaker in the shop, but when I'm on the road it's nice to have something very small and light. The Cutter Shorty is a packable bike tool that includes a chain breaker. While not quite as easy to use as a park tool, it's perfect for packing with you. That and a spare master link, and you're set.
