Missouri knife laws 2025: what are the rules for knife lovers?

A passion for knives is often rooted in a deep appreciation of craftsmanship, history and culture. For those of us who collect or regularly use knives, understanding the local laws governing their possession and use is essential. This article aims to enlighten knife enthusiasts on the specifics of Missouri’s laws. 

We’ll guide you through the state’s regulations, offering an overview of the rights and responsibilities every knife enthusiast should know about to enjoy their passion legally and with full awareness of the rules.

What are the general knife laws in Missouri?

Missouri is known for its fairly lenient approach to knife ownership. Under state law, there are no specific bans on any categories of knives, which means you can carry any type of knife, including those often restricted in other states like switchblades, automatic knives, and concealed knives. 

The freedom to own and carry a knife in Missouri is supported by both state statutes and a general respect for personal rights. 

However, while state law does not impose many restrictions, there are certain nuances and federal laws like the Federal Switchblade Act that still influence what is permissible.

What types of knives can you legally own and carry in Missouri?

In Missouri, the law allows individuals to own almost any type of knife. This includes various types of knives such as : 

• switchblades, 
• automatic knives, 
• traditional pocketknives. 

Missouri knife laws are particularly generous, even allowing the concealed carry of knives with blades longer than four inches, which is often restricted in other states.

However, while you can own these knives, carrying them in restricted locations such as schools, courthouses, and planes will land you in hot water. 

It’s also worth noting that despite the state’s leniency, there are federal regulations to consider, such as the prohibition against carrying switchblades across state lines without a proper reason.

What are the legal and illegal aspects of carrying knives?

In Missouri, the law distinguishes between various types of knives and how they are carried. Legally, you are allowed to carry a knife openly or concealed as long as the knife isn’t classified under the illegal category.

Concealed carry of knives is permissible under Missouri law, except for certain types of knives like a switchblade. The length of the blade also plays a crucial role here; knives with a blade longer than four inches may fall into a grey area under local regulations. 

It’s important to remember that while state law does not heavily restrict the concealed carry of knives, local ordinances can have stricter rules. Therefore, checking with local laws is advisable if you plan to carry a knife in different cities within Missouri.

What specific regulations exist for switchblades, concealment, and more?

As you know, under federal law, specifically the Federal Switchblade Act, certain restrictions apply to transporting switchblades across state lines, but Missouri law permits owning and carrying a switchblade within state boundaries. 

However, carrying a concealed switchblade is a different matter, as mentioned previously, and may require careful consideration of both state and local regulations.

Concealment laws in Missouri are pretty straightforward when it comes to ordinary pocketknives, typically defined as having a blade less than four inches long. These are generally exempt from restrictive laws that apply to larger or more dangerous weapons. 

Nevertheless, if you’re a fan of automatic knives or switchblades, it’s crucial to understand that while state laws may allow possession, carrying them concealed might not always be permissible.

Are there restricted locations where carrying knives is prohibited?

In Missouri, as in many other states, certain restricted locations exist where carrying knives or any weapons is outright banned, regardless of the knife’s size or legality elsewhere. Places such as schools, government buildings, courthouses, and planes are typically off-limits. 

Laws in Missouri also dictate that establishments such as bars or private properties may enforce their no-knife policies, which must be respected.

Outdoor enthusiasts in Missouri should be particularly mindful of where they choose to bring their knives. While hiking in a wild forest may seem like a perfect place to carry a survival knife, certain federal lands or state parks might have specific rules that restrict carrying even ordinary knives.

What are the consequences of violating knife laws in Missouri?

Violating Missouri knife laws can lead to serious repercussions, ranging from fines to imprisonment. 

Indeed, under Missouri law, certain types of knives are illegal to carry, especially in a concealed manner. For example, while you can legally carry an automatic knife or switchblade in your pocket, carrying a concealed knife that’s considered an illegal knife, such as one that exceeds four inches long, is not permitted and can be penalized under state statutes like 571.010 and 571.030.

It’s also important to note that Missouri knife laws vary when you enter restricted locations such as schools, government buildings, or any place where firearms are restricted. In these areas, carrying knives, whether open carry or concealed, can lead to criminal charges. 

Always check the specific laws in Missouri for the area you are in to avoid unintended law violations.

How can knife enthusiasts in Missouri stay within the law?

For those who enjoy collecting or using knives, understanding and adhering to Missouri’s knife laws is crucial. Always remember that while Missouri knife laws are fairly lenient, they do impose limits on knife ownership and usage. 

Here are a few practical tips:

• Always opt for an ordinary pocketknife as these are generally exempt from the harsher restrictions.
• If you wish to carry a knife that’s larger or falls into specific categories of knives, consider applying for a concealed carry permit, especially if you need to carry a knife concealed.
• Educate yourself regularly on updates to the law, as statutes can amend over time, affecting how you might carry or use your knife.

Conclusion

In summary, while the state of Missouri provides considerable freedom for knife owners, it imposes strict regulations where necessary to ensure public safety. Whether you’re an outdoor enthusiast looking to use a knife in a wild forest or a collector of unique types of knives, staying informed about the legal is essential.
