Colorado has distinct knife categories:
- Illegal Knives: Possession or carry of these knives constitutes a legal offense. This includes switchblades with blades longer than 3.5 inches, ballistic knives (a blade propelled by a spring-loaded mechanism), and blackjacks (bludgeoning weapons).
- Legal Knives for Open Carry: Most knives fall into this category and have no blade length restrictions for open carry in Colorado, provided they are not concealed.
- Legal Knives for Concealed Carry: Knives with blades less than or equal to 3.5 inches may be carried concealed throughout the state, subject to certain exceptions discussed below.

Blade Length and Concealed Carry
- The 3.5-Inch Rule: In Colorado, blade length is the determining factor for concealed carry. Blades exceeding 3.5 inches must adhere to these exceptions to be legally carried concealed:
- Exceptions for Concealed Carry of Longer Blades:
- Your Property: You’re free to carry any knife concealed within your home, place of residence, or property under your control.
- Place of Business: Concealed carry exceeding the blade limit is permitted at your workplace, unless prohibited by company policy.
- Motor Vehicle: A knife of any blade length can be legally concealed within your private vehicle.
- Hunting and Fishing: For these specific activities, a concealed knife of any size is permissible. This is treated as an affirmative defense if questioned by law enforcement.
Locations with Knife Restrictions
- Federal Buildings: Courthouses, post offices, and national parks may have stricter federal knife regulations. Contact the relevant federal entity or the park service for specific policies before your visit.
- Schools and Universities (K-12): Colorado protects educational environments by prohibiting all deadly weapons, including knives, on school grounds. This applies to open and concealed carry. Exceptions may exist within authorized education programs, but confirming with school administration is essential.
- Private Property: Businesses and establishments reserve the right to restrict knives within their premises. Always check for posted signs indicating any prohibitions.
Important Considerations
- Manner of Carry: The way you carry a knife, even a legal one, matters. Openly brandishing or aggressively displaying a knife could lead to intervention from authorities.
- Local Ordinances: Colorado provides a state-level framework, but municipalities can impose additional rules. Checking with city or county law enforcement will clarify any local variances.
- Example: Denver bans throwing knives within its boundaries.
- Intent and Context: Officers have some latitude in assessing the legality of knife carry. Actions suggesting an aggressive intent could lead to confiscation of even an otherwise legal knife.
Safety and Responsible Knife Ownership
- Education and Training: Invest in knife safety training and education to protect yourself and others.
- Mental State: Never carry a knife if you are mentally unstable or under the influence of impairing substances.
- De-escalation: A knife is first and foremost a tool. Avoid resorting to its use when faced with conflict. Practice de-escalation tactics whenever possible.
