My brother is a school teacher and wants to get a bunch of geodes (hollow

Wouldn't a rental tile saw work pretty well for this?

That's what I thought at first.

A saw is too slow, and it can damage the crystals inside the geode worst
than cracking them open. Pipe-breakers, or homebrewed crackers built
out of hydraulic shop presses seem to be what's used in most rock and
gem shows.
