Which of the following is considered a dangerous tool?

Knives are classified as dangerous tools due to their sharp blades, which can be used to cut or stab, posing a risk of injury to individuals. In a correctional environment, the potential for knives to be wielded as weapons significantly increases safety concerns for both staff and inmates. When assessing tools and items typically found in a facility, it is critical to evaluate their potential for misuse.

Spoons, plates, and cups do not present the same level of risk as knives. While they can be used inappropriately, their primary functions do not involve cutting or piercing, making them less likely to be categorized as dangerous. The nature of knives as cutting instruments inherently associates them with higher danger, which is why they are deemed more hazardous than the other listed items.
