Generally you need a chain tool to cut a chain, but if you don't have one, here are two methods you can use.
1- if you have a steel plate with a hole in it, you can drive the pin out with a hammer and punch. Be sure the plate is flat and rigid, since you want good support, lest you bend a plate.
2- you can grind the ends of both pins on the same outer plate down to the plate, then they punch through pretty easily and you remove the other plate from the opposite with both pins still attached. This is the normal method for large or wide industrial chains.
Of course, chain tools are pretty cheap, so the back up methods only make sense in unique circumstances.
