I recently became owner of a Black Diamond C.M. Harrison & Co Scranton P.A. Made in Germany straight Razor blade.
I have been unsuccessfully trying to restore it to it's original and proper sharpness. I have a properly lapped Norton 4&8k stone but am not able to get it to pop the hairs off the arm nice enough to progress to the next stage.
I need suggestions on what to do next. I have very likely overdone and broken the burr off but am unsure how to restore the burr with backstrokes. Any and all input would be appreciated. I have no problem making some hairs come off my arm with the blade but it is definitely just not sharp enough for beard hair. My many thanks,
