How do I use this shaping tool?

How do I use this shaping tool?

This seems silly, but I can't find a single video of how to use this. There are other versions of this tool whose "shaper" side is concave sandpaper for a certain curve, but this one is flat with little spikes.

The other side is marked as the scuffer side, and this one is supposed to be for shaping. How?
