Steel rulers with cork on the bottom will keep your rulers from slipping. I’ve had mine for about 40 years but would expect that they are still available at art supply stores. They give exceptional accuracy and are easy to keep from slipping with only gentle touch. Just as Paul said, lighter strokes is the answer for accuracy and not having the blade slip and jump the metal straightedge. I learned that from seeing some pretty nasty cuts on others who attempted to place too much pressure in just one or two passes. My cutting using this method in the past has been mostly on mat board, but I use the same technique now when cutting thin pieces of wood.

Another thought: you might also just glue a thin strip of cork on the bottom of your ruler.

Keep up your good work and blog. We’re learning from you.
