Everywhere I hear that you must not fight withe the swords. In the first place because these blades are constructed with a rat-tail tang construction. They say it's weaker, but it cvannot be anything else, a rat-tail is only more narrow than the actual blade. And that's the point with al these sword designs. Also in the movie they are not full-tang. So the following questions: Are the rat-tails from these swords one with the blade or are they weld on it??? When they are one with the blade, the only problem why we cannot fight with them is the stainlees steel, am I right????
