What is a gravity knife?

A gravity knife is a type of folding knife that uses gravity or a flicking motion to open the blade, instead of a manual or assisted opening mechanism. These knives usually have a locking mechanism in place when the blade is open.

Gravity knives have been historically used by military personnel and law enforcement officers, and were commonly associated with switchblades and other automatic knives. In some jurisdictions, gravity knives are considered illegal weapons and are subject to legal restrictions.

It is important to note that the use and possession of a gravity knife may be subject to specific laws and regulations, and therefore, it is important to know and follow the legal requirements in your specific area.
