Can I carry a knife on me?
No, not without a legitimate reason. All knives are category D weapons. Buying and keeping them is free (for an adult), but carrying and transporting them on the public way is banned without a legitimate reason. A legitimate reason is, for example, professional use (craftsman, cook) or an outdoor activity (fishing, hiking, hunting). However, wanting to 'protect yourself just in case' is not recognised as legitimate by case law — on the contrary, it suggests intent to use it against others. In short: you can own a knife, but not carry it on you without a valid reason.

⚠️ Penalties & fines
Carrying or transporting without a legitimate reason a category D weapon is punishable by up to 1 year in prison and a €15,000 fine, with confiscation.

❓ Frequently asked
Can you carry a pocket knife on you?
No, not without a legitimate reason. A knife is a category D weapon: keeping it is free, but carrying it on the public way is banned without a valid reason, like professional use or an outdoor activity (fishing, hiking).
Is self-protection a legitimate reason?
No. Case law holds that wanting to 'protect yourself just in case' isn't a legitimate reason: it instead reflects intent to use it against others. Carrying a knife for self-defence is therefore banned and punished.
What's the risk of carrying a knife without a reason?
Up to 1 year in prison and a €15,000 fine, with confiscation. Since April 2024, a fixed criminal fine of €500 is trialled in some areas for carrying a category D weapon without a legitimate reason.
Can you buy and keep a knife?
Yes, buying and keeping a knife is free for an adult. It's only carrying and transporting on the public way, without a legitimate reason, that's banned. At home, use is free.
What counts as legitimate reasons?
Professional use (craftsman, cook, fisher), an outdoor activity (hiking, camping, hunting, fishing), or justified transport of the knife (purchase, return from a cutlery shop). The context is assessed by the police and the judge.
