SKB,
That is interesting, it seems to be a useful idea, also for backing up abrasive when polishing. The one described by Rocketman could also be useful. It's amazing how different people come up with different ways to do a job. I find a Barrett(?)file very useful working around the ribs on doubles and drillings; even more than a Knife file, because it is thinner.( I can't stand in front of a vise for any length of time any more)
