What are the real strange weapons in the history of China?

I believe everyone is familiar with weapons, such as Nine-Chain Knife, Pear Gun, Zhan Ge and so on, but what we are going to talk about today are those rare weapons.

In fact, at the earliest time, human weapons were like wood, stones and even bone tools, but with the progress of science and technology, human beings developed various weapons in the war, among which many weapons with strange shapes and unpopular ones appeared. Let's list a few.

The first one is Emei thorn. Emei thorn is a very traditional weapon. As you can know from the name, it is the assassin's special weapon. Generally speaking, it is a pair, 30 cm long. Both legs are particularly sharp thorns, which can be used on fingers and rotated on hands. It appeared in the classic "Three Heroes and Five Righteousness" in Qing Dynasty, and it was the most powerful weapon in Pingjiang.

The second is the judge's pen. Similar to Emei thorn in appearance and usage, it often appears in various martial arts novels or revised film and television dramas.

The third type is the hook and sickle gun. The head of the crochet gun has a barb. The function of the hook and sickle gun is the same as that of the ordinary pike gun, and the barb can prevent the enemy from escaping. In ancient wars, crochet rifles were specially used to attack cavalry. When the cavalry enters the infantry formation, the soldiers can use the hook and sickle gun to cut off the legs of the enemy cavalry, causing the cavalry to fall and be killed. In the Song Dynasty, when Yue Fei was fighting Jin Jun, he used a hook and sickle gun to fight Jin Ren.

China Wushu has a long history, and there are countless swords, guns and clubs. There are many weapons with strange shapes in history with great lethality, so I won't list them here.
