Chained Kunai 3D model

This weapon is known as a kunai, which is a traditional Japanese tool and weapon. It typically has a leaf-shaped blade and is often associated with ninjas in popular culture. The one in your image appears to be attached to a chain, which is similar to a kusarigama, another traditional Japanese weapon that combines a sickle (kama) with a chain (kusari). However, the weapon in your image is more accurately described as a chain kunai due to its specific blade shape.
