a finer coating would be nice

The product is well made with no burrs or sharp tip but I already clearly abrasive the coarse side. Do not look one way or confused with the fine work the sides, already one can hurt you. Rough work definitely succeed quickly and well. Desirable would be a new variant on the corresponding side of the rough current fine side and the polishing side is again significantly finer. Or two files in the set - a bilaterally coarse and another Polierfeile fine and very fine coating.
