I'm starting on my first two customs right as of now, However I'm struggling to cut around the seams with the hobby knife I have for my ponies, The heads came off fine but the neck plugs will not move.

I've also managed to cut into the plastic of the ponies a little so I'm afraid to try anymore with the knife for the moment does anyone know of any other way of removing them for the time being without causing further damage or have any other tips to give to me?

Many thanks, Safty
