That method is using a very sharp Xacto-type knife to make the X cut. I
plan on doing about 10 a day over the next few weeks.

Don't skimp on the blades. You can get 100 #11 blades from Amazon for
about $10. I get Techni-Edge and they are as good as the X-Acto blades
for a buck apiece in those 5 blade blister packs.


Another option is the carpet knife and blade. You get 4 surfaces per
blade (end for end and flip it over to use the back side) and they are
made for cutting stuff like this with a more ergonomic handle. That
idea of making a jig to hold them using a 2x4 with a hole drilled in
it (snug fit on the ball) is going to save a finger. Maybe nail that
to a bigger piece of wood for stability and drill a smaller hole
through that in the center so you can poke the ball out.
That should go pretty fast.
