As of 2023, the legality of gravity knives in Missouri is a topic of interest for many residents. Gravity knives, also known as flick knives or switchblades, are folding knives that open automatically with the help of gravity or a flick of the wrist. While they can be useful tools in certain situations, their potential for misuse raises concerns about public safety and the law.

Missouri Knife Laws

In Missouri, the possession and carry of knives are primarily governed by state law, specifically Chapter 571.020 of the Missouri Revised Statutes. However, the law does not explicitly mention gravity knives, making it somewhat ambiguous.

Definition of a Gravity Knife

A gravity knife is generally defined as a type of knife that opens automatically by the force of gravity or by the application of centrifugal force. It typically has a blade contained in the handle, which is released and locked into place when the knife is opened with a flick of the wrist or other similar motion.

Prohibited Weapons

While gravity knives are not specifically mentioned in Missouri law, certain types of knives are considered prohibited weapons. According to Section 571.020(13) of the Missouri Revised Statutes, it is illegal to carry concealed any “knife, commonly known as a throwing knife, dirk, dagger, or stiletto.” This provision may potentially apply to gravity knives depending on how they are classified.

Legal Interpretations

The legal interpretation of gravity knives in Missouri can vary, and it ultimately depends on how law enforcement and the judiciary view these knives within the existing statutes. Some argue that gravity knives could fall under the category of “dirk” or “dagger,” which are explicitly mentioned as prohibited weapons.

Case Precedents

Case precedents can offer insights into how gravity knives have been treated in Missouri courts. However, as of 2023, there are no notable cases in Missouri specifically addressing the legality of gravity knives. It is essential to consult legal professionals or authorities to obtain the most up-to-date information.

Recommendations and Best Practices

Given the existing ambiguity surrounding gravity knives in Missouri, it is advisable to exercise caution when possessing or carrying such knives. It is always best to err on the side of caution and comply with the law. If you are uncertain about the legality of a gravity knife, consult with an attorney who specializes in criminal law or contact local law enforcement for guidance.

Alternative Knife Options

If you are looking for a versatile and legal knife option in Missouri, there are various alternatives to gravity knives. Folding knives with manual opening mechanisms, such as thumb studs or flipper tabs, are generally considered legal as long as they do not possess other features that would classify them as prohibited weapons.


In conclusion, the legality of gravity knives in Missouri remains somewhat uncertain due to the absence of explicit mention in the state’s statutes. It is recommended to exercise caution and seek legal advice if you have any questions regarding the possession or carry of gravity knives. Always prioritize safety and adhere to the law to ensure a responsible and law-abiding approach to knife ownership.
