This is the factory edge, and the same thing with the plywood's a little bit harder on the blades because the grains are crossed, there's glue, and there are other materials, and just this little bit of fabric that's left, there's not any visible chip out further than the fact that these are left here and once they get flaked away that'll be little pieces of scrap out but otherwise the saw has cut very clean you want to look for an immaculate cut that is an indication of a very sharp dull saw blade.
