This is what I do:
"Sand" it with some steel wool to see if the scratch buffs out.
A crack will
usually be a bit deeper
I think after a bit of buffing with the steel wool you can tell the difference between a crack and scratch, but it's hard to be honest, becasue the cranks cost good money, so you sit there trying to convince yourself that it's only a scratch.
