Personally I consider them a bit too aggressive, and prone to go for edges. I much prefer pieces of cork tile or rubber sheet on one of their arbors, to which you superglue a disc of fine abrasive paper. I also hacksawed a piece from an annealed wood rasp, and silver soldered it at an oblique angle to a short steel rod with a file handle on the other. At that stage it was for smoothing the bottom of the action recess in a gunstock, but I then glued some fine paper to a cork tile, and I can cut small pieces with an old pair of scissors, impale them on my rasp push-stick, and discard them as they clog.
