  Why are katana swords curved? This happens during the clay tempered process stage, clay is coated on the sword ridge, when quenching the blade, the part not covered by clay cools faster and becomes very hard, while the sword ridge cools more slowly and remains relatively soft and pliable, the metal blade expands and contracts with heat, so the part not covered with clay will expand more than the spine, causing the katana to bend. In summary, it is the result of differential hardening of the blade during quenching.   The curved curvature of the samurai sword-sori There are basically three types of sori, the most common one is called Tori sori, the curvature is deepest in the middle of the blade. The sword with the deepest curvature of the tip is called "sakisori", while the sword with the curvature closer to the handle is called "koshisori". It's not that more curvature of the blade is better for cutting, a good curvature is usually between 1/2 to 1", with...

  As the saying goes: "A layman sees the fun, an expert sees the way", most people are easily attracted by the gorgeous appearance of Japanese swords, but their knowledge of the blade is limited, mainly because it is difficult to obtain relevant information, and it is difficult to see real swords.   Therefore, those who like to buy either fake knives or sub-grade products with serious flaws in forging, or the knives are assembled knives, the hilt and scabbard, the eye-penetrating, the edge head, the tang, etc. are complete sets or not. Complete sets, new or old, are not easy to identify if they have no considerable literacy. Knives are usually kept in their sheaths, and high quality battle ready katana is only used when going out. Let me tell you a misunderstanding: knives and knives are two completely different fields of art, which are not absolutely related to each other. This concept must be clarified, otherwise it is easy to fall into logical errors.       ...

  It is said that there were two very famous swords in ancient Japan, one called Muramasa and the other known as Masamune. According to legend, someone once tried to test to see which of the two knives was stronger, so he inserted the knife into a small stream, and then floated the leaf to the position of the blade. It was easily cut in half, which proved that Muramasa was indeed a good knife; and Masamune was the same, when the leaves drifted past, a strange thing happened, the leaves drifting towards Masamune were not only not cut in half, but looked It looked like it was deliberately skewed, so I tested a few more leaves, and they were all far away, as if they didn't dare to get close.
