It seems that I have become the owner of a Joseph Rodgers 'Star and Cross' microtome, not a Joseph Rodgers wedge as I expected! That will teach me to check the photos more closely! The face of this 'razor' is concave, while the reverse side is dead flat. I'm wondering if this could be honed asymmetrically like a Kamisori somehow? I use both hands, so it would not be ideal on one side of my face I guess. Thoughts and suggestions?
