Yes with a jig-its a small square box from 1/4 inch plywood I made -open at top and bottom box and you use a wire cutter (mud tools) to cut both sides at once-I cut 35 today after a few minutes in the sun to firm up.
Put box over them on the bats and cut -let dry till firm relaese them and sponge edges.
These are all over the planet by now-I know mine are in Australia and europe as well as Africa and New Zealand and Japan
A Japanese potter saw mine and sent me one he knocked off a bit more elaborate with a panda on it.
