What is the blood groove (bo-hi) on the sword?
The aesthetics of ancient Chinese swords mainly include the following aspects: first, exquisite manufacturing; second, scientific modeling; third, the ever-changing decorative styles and their profound cultural symbols and meanings; fourth, powerful lethality, that is, excellent practical performance . Today I will talk about the blood groove on the common blade. Blood groove is about swords, and many people only understand it literally. As a result, the name is a little bit evil, adding a bit of mighty feeling to the sword.
The appearance of blood groove:
First, the appearance of blood groove (bo-hi) is basically accompanied by the appearance of swords. Compared with the sword, the blood groove on the sword appeared earlier. The earliest sword with bloody groove was forged by the Shang Dynasty in China. Therefore, it can also be said that the blood trough is a by-product of the invention of the sword. However, in the Shang Dynasty, the skills of sword making were not mature. For example, the swords at that time did not have a shield, and blood grooves are usually distributed on both sides of the sword on this kind of sword, and they are shallow and irregular in shape. In addition, at that time, more weapons used blood grooves were spears and Ge. For example, the bronze weapons of the Shang Dynasty (spears, Ge,Dao, jian, daggers, etc.) found in Xingan, Jiangxi and other places almost all had blood grooves. .
In addition, the blood groove is shaped like a fish-shaped geometric pattern, outlined by a sun line. The first half of the groove contains a small fish-shaped geometric pattern, and the second half is outlined into a simple and complete fish-shaped. On the inner side, there is an inner oblate ring, a semicircular concave shallow groove on the outer side, and embedded Bohua turquoise pieces. These should be regarded as the earliest physical evidence of blood grooves in the history of human weapons. As early as the Spring and Autumn Period and the Warring States Period, there were blood grooves on the bronze swords of Wu Yue and Chu, and many of them have been unearthed at present. During the Han Dynasty, it was the period when the long sword gradually replaced the short sword and became the mainstream. At the same time, the ring head sword became popular. However, the blood groove on the sword is mainly located on both sides of the spine of the sword, or on both ridges, while the blood groove of the ring-head knife is on the back of the sword.
The influence of blood groove on the performance of swords:
1. Keep the sword sharp. The sheath of some swords (especially Japanese swords) has a convex line with blood groove, which can make the blade hang in the sheath and avoid friction between the cutting edge and the sheath to reduce the sharpness.
2. Reduce weight and save steel;
3. it is to strengthen the strength of the blade, through the blood groove to form a "I"-shaped blade section, which can ensure the strength while reducing the weight;
4. Ensure balance. Since ancient swords were all made by hand, the center of gravity will be shifted. The balance of the sword can be fine-tuned through the blood groove;
The aesthetics of the blood groove is first of all technical specifications. It is a straight wooden rope. It is regarded as the specification of a wheel. Meticulousness is the most basic requirement, and the ratio of length, width and depth is more coordinated and scientific.
In ancient times, the blood groove was completely hand-made, and the craftsman’s superb skill was the prerequisite, the good intentions were the key, and the rich imagination was the source of art. See the elegance of traditional crafts.
How is the blood groove on the sword formed?
You can use a pen to draw the shape of the blood groove on the blade first, and then use a sword or saw blade to draw along the drawn line. Because the blade is slippery, it is not easy to draw out, so light and then heavy, little by little Make the mark, and finally use the tip of a half-round knife to polish along the mark until you achieve the desired effect. Of course, you can also use a saw blade or other hard things to make it. The blood trough is very slow without special tools. The main reason is that you must be careful at the beginning, otherwise it will easily get crooked.
So the answer is: planing and grinding, rather than forging that ordinary people understand.
Under the premise of completely hand-made, the craftsman’s superb skills are the prerequisite, the good intentions are the key, and the rich imagination is the source of art. It is the creator's painstaking and hard work to create, allowing future generations to see the traditional craftsmanship. Style.
