1. Overall appearance: the original badminton racket shaft and racket frame are bright and smooth, English characters, icons and other symbols are finely printed, and the double-photoetched steel numbers on the racket shaft and taper handle are clearly recognizable; However, the fake feather racket is not as good as the original feather racket in all aspects, especially the shield-shaped PBSI logo on the cone handle is far from the real one (due to the different sales areas, there is no shield-shaped PBSI logo on the cone handle of the feather racket with the steel grades of CH, th and TW). )。 2. Lithography steel number: YONEX quills and awls produced after 1999 are mostly engraved with factory numbers that are difficult to forge by advanced laser technology (commonly known as double steel number: the number on the handle of the racket is the serial number of the product, and each racket is different; The number on the handle is the product batch number, which is the same as the batch product batch number), as shown in the figure below; Most fake badminton rackets don't have photoetched steel numbers, some are printed fake steel numbers (please be sure to identify them carefully), and some fake rackets also have steel numbers, but if you identify them carefully, you will find that the font, height, width and density are different from the real ones. It is best for unfamiliar golfers to bring real rackets for on-site comparison. Please note that the early YONEX badminton racket only pressed the deeper and thicker product batch number (commonly known as single steel number) on the tapered handle. 3. Rubber particles of the threading hole: The rubber particles of the original badminton racket (also known as the protective tube) are made by injection molding, and the ends of the rubber particles are chamfered by more than 30 degrees without burrs, and basically different sizes of rubber particles are used in different positions of the racket frame. At the inner position of the racket frame where the middle and high-grade badminton racket passes through the hard line, the rubber particle end of the threading hole is V-shaped; However, the end of the colloidal particles of the fake feather racket is generally flat, with sharp edges and no chamfering, which is prone to burrs. After a period of use, it is easy to crack, wear or even fall off, and even affect the service life of the feather line. From the aspect of threading feel, taking the most commonly used YONEX BG-65 badminton thread as an example, the inner wall of the protective tube feels smooth and smooth when it is really knocked, and it is easy and smooth to wear, and the threading sound is round and pleasant; However, when the fake racket is threaded, it feels that the inner wall of the protective tube is rough, the friction is large, it is time-consuming and laborious to wear, and the threading sound is sharp and harsh. 3. Grip glue: The grip glue of the original badminton racket is thin and soft, evenly wound, flat and stable, and the plastic protective film outside the skin of the new racket handle is tightly sealed by heat shrinkage technology; The rubber of the handle of the fake badminton racket is thick and slippery, which is easy to loosen and slip, and it will be damaged soon after use. The plastic protective film outside the skin of the new racket handle is not tightly sealed, which is very different from the real one. In addition, the bar code label on the handle of the fake racket is printed coarsely. 4. Back cover of the racket handle: The Japanese letters on the back cover of the original badminton racket handle have unique fonts and uniform colors around the letters; On the other hand, the Japanese letters on the back cover of the fake badminton racket handle are rough, and there are traces of white stripes around them. 5. Racket cover: The original badminton racket cover has various styles, and the badminton racket cover of different agents is different and soft to the touch. Some YY or Unix trademarks of racket covers are also embroidered by computer. Ball racket covers produced in recent years generally do not print a single racket model, but only the racket series names, such as "TITANIUM, CARBONEX" and so on. Most of them are ordinary racket covers of the same series, and some high-end rackets sold in Japan are equipped with black velvet bags; However, the fake badminton racket covers are basically the same in material and feel hard. Most of them are printed with a single racket model, and the plastic tastes heavy. Generally speaking, as the world-renowned first brand of badminton rackets, we will take every detail of the products seriously, from product design and packaging to clear and neat printing of words and icons, and we can see the elegance of famous factories.
