Most use whatever works -- a combination of files, sandpaper, Dremel, polishing compounds etc. The tools are less important than your ability to see what mods are required, your knowledge of what is needed to make a new/rep case appear to have naturally lived through years/decades of wear/polishing & skill in wielding whatever tools used to achieve the end you seek. Like most skills, your knowledge, experience & abilities are what counts, not the tools used to achieve a result.
