I have been looking at new chains and was wondering what "mushroomed pinned" means? I am thinking that the pins have a mushroom like top on the ends to hold the plates in place, is that correct? Does that mean I would need a special chain tool to break the chain? Would I need special mushroom pins to re-join the chain together? Specifically the chain that I am looking at that says this is the KMC 810 Kool Chain.
Without knowing anything about that exact chain, I think you analysis is probably right on. Mushrooming the rivet heads would make for a chain that is less likely to come apart, but it would also take more force to press a rivet out. I bet you can break it with a normal chain tool, but I wouldn't try to reassemble it using the pin you pressed out since the flange is almost certainly shot. This sounds like a perfect time to use a master link.
Given how much of a pain that sounds like, why not just scare up some kind of normal chain that can be cut and reassambled without worrying about mushroomed heads and stuff?

I've got one an used a normal chain tool to shorten it and then used the provided master link.
I dig it. Nice chain. Quiet and smooth.
dont eat the mushroom chains. They will make you see things.
