razors, good ones. Dont heat it up it will just catch fire then you'll have a bigger mess. take a piece of galv pipe 1/2 in and put one end in a vise and clamp it down till its flat, put said razor blade in end it will sit at an angle but having the pipe at roughly 1ft or so will give you leverage to sucessfully cut out the butlle.
