An urumi is a type of weapon that comes from India. It is basically a long and flexible sword made out of metal. It is also called a "whip sword" because it has a long thin blade that is attached to a flexible handle.
Imagine a long strip of metal that can be waved around like a whip. That is basically what an urumi is. It is unlike other swords because it is not rigid like most swords. An urumi is really flexible and can be bent in different directions.

If you don't know how to use it properly, you can hurt yourself because it can be dangerous. It requires a lot of coordination, balance, and skill to create the right movements to use it effectively.
It is also important to wear protective clothing, like gloves and shoes, when using an urumi. Otherwise, you could hurt yourself or someone else accidentally.
Overall, an urumi is a very unique and interesting weapon with a lot of history and culture behind it.
