I, like Ken K use punches that I have ground and filed. Make sure, whatever implement you decide to use, that you heed Gordon's advice:
Use a dolly - I use a lead block, and be careful as you have litlle or no control over the punch.
I would also advise getting someone to hold the sax so that you have both hands free to limit any damage.
