But then, to one who habitually uses a nail and a rock as a chain tool
the use of proper tools is probably a mystery.


Try to differentiate between an outdoors emergency situation and the
workshop in the garage. It's not that difficult.

Which is hy mose of us carry a small tool repair kit that includes a chain-breaker. That way a broken chain isn't an ememrgency and a repair only takes a few seconds. After all seconds count when you're beig stalked by mountain lions or other hungry critters doesn't it? For someone who either breaks chains a lot or often comes across people with a broken chain (bother very rare where I ride even on the technical trails) it ONLY makes sense to have a chain breaker and spare link(s)and quick-link WITH YOU.

To be honest using a rock and rusty nail to repair a chain in the field sounds like something an armchair bicyclist would think up. Such a repaired chain would most likely fail again after only a short distance. Believe it or not there's good reasons why chain breakers are used to fix a chain.
