Been trying some experiments here at Seraphim Laboratories...
Here is a pic of a razor edge before, and after a shave. Includes pre-and post shave stropping on HA bridle leather strop. Edge was finished to 1um lapping film with some Cromox hanging stropping to finish it off.
Also added a pic of the edge after 4 shaves, with various strops used before/after shaving. It appears the edge is at about the same lavel as after a single shave.
