Need to cut an 1.5" X into 96 tennis balls. (To attach to classroom

So far, a box cutter is not getting it done, neither a small "cutting"
wheel from a dremel kit

Best so far is with ball held in a vise, and using a miter box saw to
cut 2 1.5" slits in ball to form X. But this is a bit tedious for 96 x 2
cuts.

Thought of a table saw, but fingers would be too close to blade for my
comfort

Tried looking for a dremel type cutter that would go in a drill motor,
but haven't seen anything I want to pay for if it does not work any
better than miter saw.

Any suggestions ??

Punch a hole into them with a knife, then use scissors or tin snips.

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.
