Hey, just noticed this thread.
Wire cutters may be up to the job if they are a good sturdy pair and you have a good strong grip. I know I can cut fairly well with mine but I used to metalwork so meh.
They will leave a sharp ragged edge though, so you will need to smooth it out with a file or something.
A dremmel (or similar) with a metal cutting blade would be your best bet if you have one.
