First look at the overall appearance: the original badminton racket shaft and racket frame are bright and flat, and English characters, icons and other symbols are clear and tidy; However, the fake badminton racket is not as good as the original badminton racket in all aspects, especially the shield-shaped PBSI logo on the handle, which is far from being clearly visible. In addition, the factory number (commonly known as steel number) is engraved on the symmetrical plane or the racket shaft of the original feather racket handle PBSI logo, and the newer original feather racket handle and racket shaft adopt the advanced photoetching steel number which is not easy to forge (double steel number: the number on the racket shaft is the product serial number, 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 feather bats don't have factory numbers. (Please note: non-SP feather bats, such as TW and HK feather bats, may not have shield-shaped PBSI logo on the conical surface of the handle. )

Second, look at the line hole rubber particles: after the line Kong Yuan rubber particles are put into the racket frame, the inner ends are not cut, and rubber particles with different sizes are basically used in different positions. The line hole rubber particles are injected with a mold, and the two ends are chamfered at 30-45 degrees. At the position where the middle and high-grade racket frame crosses the hard horizontal line, the rubber particles in the thread holes inside the badminton racket frame are V-shaped; However, the rubber particles of the fake feather racket are usually cut after being installed, and the rubber particles of the same size are basically used in different positions, and the ends of the rubber particles are flat without chamfering.

Third, look at the handle rubber: the original feather handle rubber is thin and soft, evenly wound, flat and stable; The rubber of the handle of the fake badminton racket is thick and slippery, which is easy to loosen and slip, and will soon break after use.

Fourth, look at the back cover of the racket handle: the colors around the Japanese letters on the back cover of the original feather racket handle are uniform; On the other hand, the Japanese letters on the back cover of the fake feather racket handle can see long white marks, which are rough.

Five, racket sleeve: original badminton sleeve styles, different agents have different badminton sleeves, soft to the touch, some YY or Yonex trademarks outside the badminton sleeve are also computerized embroidery; But there are differences between fake badminton rackets and various types of rackets.
