I once heard it said that there is a tool for everything and every purpose. There are tools for lifting, tools for opening things and tools for cutting. As I have mentioned, I am interested in learning new things, and rotary blades are a new thing to me. I have thought of the various uses for a rotary blade. The first things that come to mind are paper, plastics and fabrics. I think that using a rotary blade on paper and plastics will give you a more precise cut than scissors or other types of sheers. Can you think of uses for rotary blades? Let me know.
