Problem is, breaking chain is a real pain no matter what tool you use. I use one from TSC and have never had to grind a chain yet. I often end up gripping the link with vise grips and twisting back and forth to finish pulling it out. The problem seems to be that the pin pusher in most or all breakers is always a bit too short. One way of extending the reach of the breaker's pin is to get the pin started, back off, put a tiny ball bearing in the hole, then resume pushing it out. The bearing will extend the breaker's pin reach.
