Kis is a type of weapon that comes from the country of India. It is also called a katar or a katara. The kis is like a small sword or knife, but it is held in a special way.
Instead of holding it like you would hold a regular knife with your fingers wrapped around the handle, the kis is held with your fingers going through two holes in the handle. This helps the person using the kis keep a really strong grip on it, which is important because the kis is used for fighting and self defense.
The blade of the kis is sharp, which means it can cut through things easily. The person using the kis can use it to stab or slice at an enemy who is attacking them, or to protect themselves from danger.
Some people think that the kis looks really cool or shiny, so they collect it and keep it in their homes to look at. Others use it for special ceremonies or dances. But mostly, the kis is used as a weapon to protect people who need it.
