National Investigators Exam (NIE) Practice Exam

Which of the following is an example of an offensive weapon made for causing injury?

1. Butterfly knife

2. Broken bottle

3. Chair

4. Screwdriver

The correct answer is: Butterfly knife

A butterfly knife is specifically designed for rapid deployment and ease of use in a confrontational situation, making it an example of an offensive weapon created with the intention of causing injury. Its design allows for fast manipulation, which can be used in aggressive actions. Unlike tools or everyday items, a butterfly knife's primary function revolves around its capabilities as a weapon, given its sharp blade and folding mechanism, which adds to its compactness and portability for potential harm. Other choices may have the potential to cause injury but do not primarily function as weapons. A broken bottle can certainly be dangerous when shattered, but it’s more a consequence of an action rather than a designed weapon. A chair can be used in a fight, yet it is primarily a piece of furniture, with no inherent design as a weapon. A screwdriver is a tool intended for mechanical purposes, though it can be used aggressively in certain situations. The distinct design and purpose of the butterfly knife make it clear why it is categorized as an offensive weapon intent on causing harm.
