Regarding the "push the pin out" and the Dark Soul tool: My experience is that once you use a Dark Soul tool to break heavy duty #25 chain (e.g. Vex), you will not be able to use it conveniently on regular duty chain again, because the pin will be pushed out before you hit a stop. For precisely this reason, we have two dark soul tools, one tagged "HD only" and the other "RD only". We keep the HD chain in one bin, the RD chain in another bin, and the tools in their respective bins. So far, the "RD" tool is still in usable shape. If the tool gets messed up, I suspect that we shall simply toss all of our RD chain; it'll be less expensive than getting another tool every year or so.
