My brother had never used a rotary. He was cutting marine vynil and it was skipping so he thought 2 blades would cut better and that stuff was thick. Well 2 blades did not work out-the skips only got longer. He had pushed down to hard and the screw on the knob had actually bent. He tried to straighten it but it broke the plastic. After that I cut the rest of the vynil with a new rotary.
