When the burr is formed, it starts to feel rough. When it feels like it’s digging into skin, it’s sharp. It’s a very subjective thing though, everybody has different fingers.

Is way better to draw your finger perpendicular to the edge to feel the burr. That way you don’t cut yourself on the edge or the burr itself.
