The Park CT-3 will do any normal 1/8" chain, it's only the ones with very thick plates that you need a different tool for. You're probably not going to find too many of the thick 1/8" or 3/16" chains at the dump, but maybe the trash in Finland is different from the trash around here...

The tool I carry on a ride, if I carry one at all, is the Wippermann, and it's a good one.
