Is there an official way of getting them off without scratching up a shaft
by the way?

Destroy them, replace them with new ones. They usually suffer a loss
of springiness in being removed anyway.

Easiest way is to cut their circumference with a pair of side cutters.
Once they're no longer a ring, they lose much retention ability. If
you cut them twice, they fall in half.
