These swords are the first made for a series. They are 100% hand made and the most expensive swords to make. We get these swords, examine them, and then make changes (if we want) for a public production run. For example, maybe these swords have a different target weight, a different grind or steel, different handle configuration, or we just wanted to test certain things on a blade out to see what it was like. These are all excellent swords and all 100% unique. See the sword details for more info on how each is unique.
