The tools I use most:
Hobby knife with #11 blade (buy blades in a box of 100, you will use them)
Sanding bars

At the local hardware or paint store you can get cheap, clear plastic, drop cloths. Cut a piece to cover your plans. It iseasy to see through and does a good job of protecting the plans. I like it better than waxedpaper but it is strictly a personal preference.
