I would like to get some advice about a hone I bought on ebay. It is aVintage Tonsorial Gem Double Side (Combo) Razor Hone. The person selling it didn't have the grain. I'm wondering if this stone alone is suitable for honing my straights? Or if I will need to get other stones as well? Oh also I have a strop in the mail as well and I know I will also need to use that. Just hoping I don't need to buy another stone. Thanks for your help
