You need lots of variety, so some of as many different sizes, cuts and shapes as you can find will be useful. Files really are cheap for the smoother cuts. The coarser the file the harder it is to keep it uniform, therefore they cost a lot more, rasps especially!
Good draw-filing type technique will go a very long way toward keeping the surfaces true...
