I currently use a #9 rasp for curves/shapes on hardwood and want to use something with a smoother cut to follow it up with. If I am using a #9 (Liogier) now for the first pass, can I jump up to a (say) #12? Also, I would like to have a decent wood file to use on mostly hardwood and have no idea as to a decent source for this. I believe a double cut type would be best but can easily be convinced to try something else. I saw an advert for Nicholson, but wonder if their wood files have gone the way of their metal files.
