The first users of trademarks were sword makers of Imperial Rome. First writings on sword blades date back to Roman Empire (I–V century AD) and mainly inform people of the name of the sword maker, for example RANVICUS. Such markings can be called trademarks as the craftsman was personally responsible for the quality of his products and the buyer could make his choice based on the name on the sword.
