I have one of those rulers with a lip on it that snugs up to your ruler when cutting. (If that makes sense). I always use this one and like the way it stays straight. I don't know if they sell them anymore. If you have a Menards in your area, they carry the suction handle thingy in their bathroom accessory area. Works wonders and it's so much safer to have your hands and fingers out of the way. Not to mention they are sooo cheap there!!!
