Lynn,
Just tried out the Hamburg Ivorine and the Filarmonica razors you honed for me. Wow! I never had great luck with Filarmonicas, maybe the edge is too fine, maybe the steel is too hard....but I could never get them where I wanted.
What did you use to get them to their incredible sharpness? I am sure other would be cusriopus as to your approach to evaluation and sharpening when you receive a customers razors.
Thanks,
Tony
