A pipe cutter can leave some very nasty sharp edges on the rim of the ring. A hacksaw would leave some nasty burrs. So we need to get them off.

I tried 3 different bits on my dremel trying to find one that worked. In retrospect, a simple metal file might have worked better, especially as it can get difficult to hold a ring while grinding at it with a 20,000 RPM tool grinding at it fruitlessly. I ended up using a sanding band attachment, which took a good whack at it. A grinding stone was worthless, and a sanding disk was not up to this task.

Make sure to grind not only the inside, but also outside edges. One can still be cut by the part fo the ring away from the finger.
