Since this thread has gotten out of New York let me put my two cents in. We use a chain pin removal / installation tool. It allows us to extract a pin and then re-insert it. There are two advantages to this. First, if someone breaks the chain the wrong length, no problem, we just reinsert the pin and restore the chain to its original length. Second, we don't need master links. By being creative in our mounting we can tension the chain which is a continuous loop so we don't have to worry about losing a master link during game play.
In addition to all that, once you get the hang of it, I think it's a lot easier to use than the traditional chain breakers .
