The Japanese sword is the kind of art that has grown over history. Swordsmiths over the years would make minimal changes to the blade’s curvature, the Hamon, length, width, and all the other detailed features to please the sword’s owner and let the sword hold its own identity. That is why Katana has become so beautiful. In every part of the blade, you see the swordsmith’s intent and Samurai’s love and aspiration for Katana.
