If you want to try without a chain breaker, you'll want a heavy vise and a punch that's a bit smaller than the pins in the chain. Open the vise so it's slightly wider than the pins, then have someone hold the ends so they don't turn the chain. It only takes a few strong hits to get the pin to move, and it's easier once the top is below the surface of the link. We've never had a chain breaker, and it's always worked for us.
