I know you've likely heard me say this before, but I feel very strongly that at the very least you need to use your full last name. MANY times over the years I have had people stop by the shop, with a knife that only had initials or some obscure logo on it, asking me if I knew who made it, or could help them find the maker..... so they could order/buy another knife. With only initials or some logo marked on a knife, its impossilbe to know exactly who made it, and therefore impossible to find the maker.... If they can't find you, they can't order/buy another knife from you.
