What is a village demon knife? Is it too big or a knife or something?

The village is actually not a knife, but the name of a casting clan. It casts knives, guns, arrows, etc. An arms manufacturer, so to speak. Tokugawa Ieyasu was named as the "demon knife" because several relatives, including himself, were injured or killed by the weapons of the village chief, and he realized that the weapons of the village chief were similar to those of his own family, so he began to destroy the weapons of the village chief and strangle the villagers. The reason why the present village is so precious is not only because the quality of the village is good and rare, but also because under the strangulation of Tokugawa, the villagers in the village changed their names and hid themselves, and their works did not dare to write about the village. More importantly, other anti-Kant forces from all walks of life have carved "villages" on their weapons to improve their morale, so it is difficult to distinguish villages. In the village, there is a way to create the "blade of chaos". It is said that this technology cannot be copied now. So the village is both a knife and a knife.
