How to cut plastic spoons without splitting?

Make sure your scissors are nice and sharp. This should keep the spoons from splitting.

Very carefully.... I would try to put them in HOT WATER first, to build up a weakness, and this should really help. I don't mean BOILING, I said HOT., ok? Tell us how this comes out, or do this several times, the more you do this the better the results, ok?

Also, cut them off a little further from the bottom of the spoon itself.

Try using an exacto knife

I've heard that using a blowdryer to soften will help cut it and mold into the shape you need- have fun!!

I would try heating an exacto knife or tiny saw blade in a flame. Cut/ melt with that.
