still havent got around to doing this.....still waiting till get the rest of my tools but i went ahead and bought one of those hand held styro cutters..........FAIL. haha, i guess they only work good with "STYROFOAM" brand foam. it works but its to flexible and doesnt really cut all that great. its kinda just like a real small metal tube, so im going to try and smash it flat all the way down so it has more of an edge and see if that helps. if not im going to cut it down to like an inch and a half long and see if that helps....
