Hone it and use it.
As one bladesmith told me: another name for something that you can't use for one reason or other is 'useless'

Sometime ago I almost bought a roman era steel razor that I wanted to restore and put in my rotation. I was outbid at 140 euros by a museum director who would probably be revolted by what I was going to do.

I asked 2 respected bladesmiths (who would they be now... ) what they would appreciate more (assuming that they would know): to have one of their razors up in a display case 200 years after their deaths, or to have someone clean it up and use it.

They both chose the latter.
