It's nothing special, just one of the first I found on Amazon.

Are you using cardstock or regular printer paper? I've noticed that the punches can't really do thin paper very well because the paper will cumple and jam before the blades can do the work. I print all my token and paper miniatures onto 110 lb. cardstock and the punches seem to work much better.

I've also noticed that if I try to punch a hole too close to the edge of the paper it can still crumple and won't cut, so the tokens need spaced out a little bit.
