Good afternoon, I hope someone can advise me about a vintage razor I have just purchased, it's a "Golden Spur Razor" made in Sheffield, England. It appears to have a slight "Smile" I think that's what you call it. I have attempted to hone it and it appears to be quite sharp. Haven't shaved with it yet. Am I wise to continue with trying to get the blade completely flat? As I am completely new to honing your comments and advise would be much appreciated. Thank you in advance for your time..
