Good afternoon. I am a newbie and recently bought my first (and only) strop from SRD. A 3" hanging "natural" leather with their premium linen back. During my first couple of shaves, I put a couple minor nicks on the strop near both ends (probably occurred when I flipped the razor to start the new direction). Was thinking that I could sand out the nicks but was wondering what grits I should use. Second question, what is the "best" conditioner to apply to the strop to soften and "break-in" the stop (the natural leather is relatively stiff)? Thank you for all your help! Ed
