Punch a hole into them with a knife, then use scissors or tin snips.
It comes in two pieces - is installed and turns into 6 or 8 very quickly
I tried this. Scissors don't work, you can't get them far enough in. Tin snips did work, but I went back to the utility knife. You had to start with that anyway, and once you'd poked it through it was just as easy to make another cut with the knife. I've done a bunch of these, it's just not all that hard.
