another useful tool is a WHITE emery board or a small bit of WHITE sandpaper (fine) glued to a popsicle stick. If you forget to change your blade and a fuzzy edge, even the bone folder will not work to clean it up. If you are careful and go at the same angle you can lightly sand the fuzzies off. DO NOT use colored ones. They leave the same color they are behind. It also works in those corners you left a slight bit of material in if you don't get it cut just right.
