Am I allowed to carry a knife in public in Denmark?
Only with a recognisable purpose — otherwise carrying a knife in public is forbidden. Under the Knife Act you may not carry or possess a knife in a public place, a school or a leisure facility, unless it is as part of your work or for hunting, angling, sport or another recognisable purpose. No knife is automatically legal — not even a small folding knife, because it is the purpose and not the blade that decides. Knives with a blade over 12 cm also need police permission, and flick knives, gravity knives and butterfly knives are always forbidden. The trap: take the work knife on to a bar and the recognisable purpose lapses, even though it was legal at work.
📋 The rules
- Only legal with a recognisable purpose
- Legal for work, hunting, angling or sport
- No knife is automatically legal — a concrete assessment
- A blade over 12 cm needs police permission
- Flick and butterfly knives are always forbidden
🔓 Exceptions
- A craftsman or chef may carry a work knife, also to and from work
- A fishing or hunting knife to and from angling or hunting is legal
- The purpose lapses somewhere with a risk of conflict, such as a bar or nightclub
⚠️ Penalties & fines
Carrying a knife illegally can bring a fine, up to 4 months prison, or up to 2 years in aggravated cases. In practice the fines are about 3,000 kr the first time and 10,000 kr the second, so a repeat more than triples the price. What people do not see coming is how easily a lawful purpose disappears: the craftsman with the knife in his bag on the way home from work is covered — but walk into a bar with it and the purpose has lapsed, and that is exactly what counts as aggravating. A blade over 12 cm also needs police permission, and flick knives are banned outright.

❓ Frequently asked
Can I carry a knife in public?
Only with a recognisable purpose such as work, hunting, angling or sport. Otherwise it is forbidden to carry or possess a knife in a public place, a school or a leisure facility — including an ordinary kitchen knife.
Is a folding knife always legal?
No. No knife is automatically legal to carry, not even a small folding knife. It is the purpose of having it on you that is assessed concretely — not the type or the size of the knife alone.
Which knives need permission?
Knives with a blade over 12 cm need police permission. Flick knives, gravity knives and butterfly knives are always forbidden without permission, whatever recognisable purpose you may claim for them.
Can I take a knife to a bar?
No. The purpose lapses somewhere with a nearby risk of tense situations, such as a bar or a nightclub. The work knife in your bag becomes illegal the moment you walk in through the door. The knife itself does not change.
What is the penalty for carrying a knife?
A fine, up to 4 months prison, or up to 2 years in aggravated cases. In practice the fine is about 3,000 kr the first time and 10,000 kr the second time you are caught carrying the knife. Each case is assessed concretely.
