Here is a USB Microscope Photo (250X) of a strop rolled edge.
You can see the reflection right up at the apex as it rolls away from the bevel angle.
The problem I’ve found with a rolled edge is the only way to correct it is to reclamp the knife and do a touch-up with stones to restore the bevel integrity. With stropping I use the rule, “lower angles are always better”. With the Wicked Edge I strop at 1-1/2º to 2º lower than I sharpened the knife.
In the kitchen when I use a paddle hand strop for touch ups. When done properly I find it’ll bring a nice sharp edge back for a time. I try to keep the blade relatively flat when using it to avoid rolling the edge. The edge in the photo I rolled using a hand strop at too high an angle.
