The assassin's Creed's sleeve sword is described in a relatively stiff way. If you want to wear it, you even need to break your ring finger. Because in the game, the sleeve sword is extended to the rope and wired to the ring. The ring is a touch switch, worn on the little finger, and bend the palm of your hand to pull the rope and pop the sleeve sword. The sleeve sword is installed outside the arm. He bent his palm and his ring finger blocked the sword. The game gave a scary setting, and wanted to cut off its fingers and also made a name for the cut off fingers. Call it a promise from the assassin to his own creed. Don’t be serious when playing games, believe this setting for now!

Xujian has indeed appeared in history, both at home and abroad. In China, it is called Xiulijian or hand-thorn. The sword's knife is similar to the current switchblade, but it uses a spring-loaded knife. Not many people use it, but there are indeed. Because the palm of his hand is indeed likely to be injured by his own knife, the Xiujian was mostly used by skilled assassins to assassinate and self-defense, and is a type of hidden weapon. The Xiujian is extremely impractical, not as good as the short, small one-piece dagger that is easy to hide, and its practicality is even more untold. The Xiujian is a very large tool. After wearing it, the hand becomes thicker, which is very obvious. Every move may be exposed anytime and anywhere. The security is also not very good, because there is an organization that may mistakenly make a knife. For assassins who want to keep their operations confidential, it is to expose their intentions.

In Assassin's Creed, there are also sleeve crossbows. There are also descriptions in this martial arts, but it is difficult to find a prototype in reality. First of all, no one is willing to use the power, and it is better to throw a flying knife and kill it. Like Xiujian, the game adds many dazzling features, but it is purely a fantasy. In reality, no matter what method is designed, the things that come out have no practical value. In principle, some people think it makes sense. How to fold the knife can still maintain straight stabs and sweeps, but how to use it is in the game. In reality, if you want to use it, it is the same as tying a dagger in your hand. If it is really big, it will not be more effective than those warriors who use kitchen knives to chop around. It can be said that reality can only be referenced. The starring Xiujian is just able to hide. As an assassin, you need to lurk in secret, and the target will kill with one blow. If possible, abscond. It is extremely unrealistic to kill thousands of people like in the game. There are no assassins in history with similar tools, let alone such complex items.
