IF your razor isn't shave ready, it's fairly easy. Place the edge down on a flat surface that has light coming from behind. If there is light coming from the middle and not the ends it's frowning. If there's no light in the middle but light at the ends, it's probably smiling and if there's no light all along the edge, then the edge is straight.

I would use a piece of glass, mirror or such as the flat area as it doesn't get much flatter than that. If there are reflections in the way a piece of dark paper could be used.

Over Simplistic? Yup! But it will work.

OH! If the Razors shave ready then you need to be very careful so you don't mess up the edge.
