What type of item is categorized as a 'projectile bolo'?

A projectile bolo is specifically categorized as a type of chemical light. These items are designed to illuminate an area effectively by emitting light when deployed, often used in various tactical and operational scenarios. The design and functionality of a chemical light enable it to be launched or thrown, providing visibility in settings where traditional electronic lighting might fail or be impractical.

Chemical lights, or "glow sticks," contain substances that produce luminescence through a chemical reaction upon activation. Therefore, the classification of a projectile bolo as a chemical light aligns with its purpose of providing illumination in a deployable form, essential for visibility during operations or emergencies. This characteristic distinguishes it from marking tools, fastening devices, or cutting tools, which serve very different functions and applications.
