So true! I don't mess with anything like blades. I've seen some pretty bad cuts with dull blades. I was at the drs ofc. the other day and sat next to a woman who ran a dull blade up a ruler. It slipped and went right up and nearly severed her thumb. She kept it but it was touch and go. She didn't want to reach over a foot to use her cutting glove. few thousand dollars later!
