Whether it's performance, competition or practice, you need a handy Tai Chi sword. The sword is easy to hold and comfortable to use. Besides being easier to practice in the sword, it can even affect the mood when practicing the sword. Here is a brief introduction to the common Taiji sword: 1. The main materials of Taiji sword are carbon steel and stainless steel. After heating, forging and quenching, carbon steel has better strength, hardness and toughness than stainless steel, and can be processed very thin, especially after sharpening, but it is easy to rust. In order to prevent the blade from rusting, the surface of carbon steel is plated with a chromium-nickel coating, which is as bright as new after polishing. As long as the coating is of good quality and does not fall off, it will generally not rust. There are many kinds of stainless steel materials. According to the content of nickel and chromium in the material, its rust prevention degree is different, and its surface brightness is slightly darker than that of chromium-plated material. 2. There are soft sword and Hard Sword in soft and hard aspects. Soft sword is suitable as a sword for competition. Especially in martial arts competitions, the length of the sword body is mostly thin, and it shakes when there is noise. Taiji sword is slightly harder than that used in martial arts competitions, and its body is thinner than a quarter of its length. Bending at 90 degrees on the length of about 20 cm can have a good shaking effect when doing the power action of the sword. The body of a hard sword is straight, the thickness of the sword is thick, and it stands at the tip of the sword without bending. 3. From the form of sword ridge, there are two kinds: flat ridge and vertical ridge. The flat ridge is the sword ridge, which is formed by the intersection of two planes forming the blade on the sword surface, and the sword ridge is not prominent. The vertical ridge is the protruding shape at the ridge of the sword, which makes the sword look straight and solid and is deeply loved by professionals. However, due to the complicated manufacturing process, the price is higher. 4. According to the difference in weight, the weight of the sword is different according to the length of the sword body and personal preference for the hardness of the sword. Generally, the sword used by women is slightly lighter than that used by men, about 0.6 kg, and the sword used by men is about 0.7 kg. You can choose a heavier sword in practice, and a lighter sword in pursuit of effect in competition. 5, the choice of sword. First, determine the material, hardness and ridge height of the sword according to your own hobbies. Secondly, the length of the sword depends on your height. Generally, the sword is held in the left hand, and the blade is attached to the back of the forearm. The left elbow is slightly bent, and the tip of the sword should not be lower than the upper edge of the ear. Hold the sword in your hand, straighten your arm, erect the sword, and carefully observe whether the blade is straight or not. Especially that thin area in the front of the blade. Stand the tip of the sword on the ground, check whether the curvature of the front of the sword body can reach 90 degrees, then straighten your arm, stand the sword, observe whether the sword body is still straight, and repeat it several times to determine whether the toughness of the sword is good. If the sword body is found to be bent and rebound badly, it proves that the material toughness of the sword itself is not good, or the heat treatment process is not excellent. Carefully observe whether there is a sudden thinning phenomenon at the junction of blade thickness or thinner than the tip of the blade, which is the poor quality caused by the processing technology. Check whether the hilt is firmly installed without looseness, rotation and burr, and the connection between wooden hilt and metal parts should be smooth. The hilt should not be too long. Hold the sword in your right hand and pull the sword flower left and right. Don't let the hilt get in the way. The pattern on the armguard is dispensable, just hold it properly. Another important thing is the counterweight of the sword. It is better to balance the sword body with the index finger supporting the plane of the sword body, and keep the index finger away from the armguard. The blade should not be too sharp, the tip should not be too sharp, the blade should be slightly curved, and the width difference between the upper and lower sides of the blade surface should be natural and slender. Also pay attention to the tightness of the sword and sheath, that is, it should not be too loose or pulled hard. The spikes of the sword are decorations of the sword. In the past, those who said prose hung their ears, while those who said martial arts hung their ears. The spikes of Taiji sword should not be too long. Choose short spikes, and the material of spikes should not float lightly. The color is best matched with the clothing, with great contrast and bright spirit. Chi Jian made of carbon steel or stainless steel needs maintenance. People's hands are sweaty. As long as they touch it with their hands, they will leave their fingerprints. Even stainless steel and chrome plating will turn black and lifeless after a long time. It is best to wipe it with cotton cloth or velvet after each use. The sword is as radiant and full of vitality as a human being. Tai Chi Sword Choosing Common Sense Tai Chi Sword Choosing Common Sense How to Choose Tai Chi Sword? What kind of Tai Chi sword is the top grade, and what kind of Tai Chi sword is most suitable for us? Let the author answer your questions step by step. First of all, it is best to choose a standard Taiji sword, which is our common long sword with sheath, but there are many styles of this sword. When choosing this sword, we should pay attention to the following standard requirements: 1. The suitable weight should be balanced with the tail of the hilt. The test method: hold the body of the sword with the fingers of the right hand (index finger and middle finger) one inch away from the armguard, and if it can be balanced, it will be the standard. Second, the tip of the sword is basically not bent. Test method: stand the tip of the sword on the ground. If the sword is basically not bent at the moment when the hand is released, it is the standard. Thirdly, the toughness of the blade is 90 degrees, and the test method: pinch the tip of the blade with your fingers and bend it. If you can bend to 90 degrees, basically no higher than 90 degrees is the standard, too soft and too hard is not appropriate. Fourth, Tai Chi sword holds the sword in a posture, and holds the sword close to the back of the arm. If the tip of the sword is higher than the earlobe and lower than the eyebrow eye, it will suit your body shape. Fifth, the weight of the standard Taiji sword is generally around 600g, and the weight of the sword varies slightly depending on the height, generally within 100g. Third, long swords can be divided into two types according to their ridges: flat-ridged swords and ridged swords. A ridged sword is the ridge of a sword, that is, the middle part of the plane where the sword body is located is convex, and a flat ridged sword is the ridge of a sword, that is, the middle part of the plane where the sword body is located is flat. The ridge of the standard Taiji sword is convex, that is, the ridge sword. Generally, the price of ridged sword is higher. In addition, the materials of the sword body are mainly stainless steel, carbon steel and manganese steel. Ordinary materials are mainly made of stainless steel. The advantage of this sword is that it won't rust and is easy to maintain. But some friends will misunderstand the stainless steel sword and think that it is made of pure stainless steel. In fact, the stainless steel blade is made of stainless steel, but the material inside the blade is iron, so casting naturally has its own reasons: First, the toughness requirement of Taiji sword is beyond the reach of pure stainless steel. Without toughness, pure stainless steel can't meet the requirements of the above-mentioned 90-degree standard toughness of the sword body. Second, the weight requirement of Taiji sword is beyond the reach of pure stainless steel. Stainless steel is a relatively light metal. If it is pure stainless steel, it can't reach the standard weight of 600g. In addition, manganese steel and carbon steel are metals that need careful maintenance. Blades made of this material should be wiped clean with cotton cloth before each use, then wiped with cotton cloth after use, and then oiled (engine oil, walnut oil, vaseline oil, etc. ) and sheath, otherwise it will rust. Manganese steel and carbon steel belong to lighter metals, and the whole handle will be slightly lighter than the stainless steel sword of the same specification by about 30 grams, but it will not affect the use.
