Which knives are illegal in Denmark?
Some knives need a police permit even at home.
Short answer
Some knives and bladed weapons need a police permit just to buy, own, carry or use them in Denmark. The list covers blades over 12 cm, knives with a crossguard made for stabbing, switchblades and gravity knives, butterfly knives with a two-part handle that open with one hand, and knives worn on the neck or shoulder that can be drawn with one hand. Throwing stars, throwing knives, throwing axes, sword canes and other blades disguised as another object are also on the list. A credit card knife counts as a blade disguised as another object, so it needs a permit too.
Why
- The permit rule applies everywhere, not only in public places.
- One-hand butterfly knives and switchblades are on the list.
- Hidden blades like credit card knives need a permit.
Details
Kitchen, hunting and work knives over 12 cm do not need a permit when they are designed for that use.
Tip
Do not buy a butterfly or credit card knife as a souvenir abroad and bring it to Denmark, as importing these knives also needs a police permit.
What may differ
The Minister of Justice can add rules that ban more types of weapons, so the list can grow.
Common misconception
If a knife is sold openly in a shop abroad, it is legal to have in Denmark.
What actually happens
Danish law decides: butterfly knives, switchblades and hidden blades need a Danish police permit, wherever you bought them.
