I used the razor that came out at Rc 50 this morning. It was a bit tuggy, it had about two weeks use since the last refresh. Two weeks seems to be the limit before it needs refreshing. The good news is, that it is easy to refresh. I did 25 on flexcut gold, 50 on boron carbide 1.8, 50 on linen then 50 on plain leather. All of this was on hanging strops. The resulting shave was very smooth.
I know all of this goes against prevailing wisdom, but it works for me. I really like pasted hanging strops. I also like the feel of the 1.8 boron carbide for the final abrasive.
I am not saying that I do not want to improve my heat treating process. I am just saying that the soft deformable blade refreshes easily.
