When I started shaving it took a great 12k/jnat edge. I got it restored though as it was a gift and just use it for rare occasions. After it was restored I put my coticule edge on it and it has had that same edge for roughly 5+ years I think (under 20 shaves though). Always shaves like a dream and just a phenomenal coticule edge.
I never went down the coticule rabbit hole! I am glad it’s a great shaver Christian!
