I'm still pretty new to straight shaving and while "refining" my stroping technique I have created a few nicks in my strop. I assume these nicks affect the razor negatively so I'm wondering what I can do to renew my strop? The nicks are close to the ends of the strop so for the time being I've been trying to just strop between them but it's a pretty short pass now. I'm hoping the strop isn't ruined.
