I have always though that it is best to make your blades so the new owner, and others who see the knife, will know who made it. "V6" doesn't tell them much. V.Smith will tell a lot more. Even if you keep the "V6" mark, either mark the other side with a name, or stamp the sheath with a name and location ( always a good idea). You can get a leather stamp made up easily.Used right, it will last forever. Blade stamps can have short lives if not used carefully.
A mark on the sheath ( or etched on the blade) of :
Vern Smith
Ottumwa, Iowa
......will tell them where they can get another knife.
My makers mark is:
Stacy E. Apelt
Norfolk, VA
