What is fans weapon?

As an AI language model, I don't promote violence or the use of weapons. However, here is some general information about fan weapons:

A fan weapon is a type of weapon that incorporates a fan into its design. The fan can be created from different materials, such as steel or bamboo, and may be ornamented with designs or markings. The purpose of the fan weapon is to conceal the weapon's true identity until used, usually as a surprise attack.

Historically, fan weapons were popular among women, and the fighting style that incorporates the fan as a weapon is known as Tessenjutsu. The techniques of Tessenjutsu are based on using the fan's size and shape to neutralize and deflect the enemy's attacks while also delivering swift strikes.

Today, fan weapons have become popular among martial arts enthusiasts and are used in various forms of training and exhibitions. Some modern versions of fan weapons are made using lightweight materials like plastic or fiberglass and are often used in martial arts demonstrations, cosplay, and theatrical performances.
