Carrying a knife in France: what the law says

Category D covers very different objects. In its answer to a written question tabled in the French National Assembly, the ministry recalls that the traditional pocket knife is treated as a category D bladed weapon, in the same way as axes, machetes or daggers.

The rules separate two situations. Buying a knife and keeping it at home is free for an adult. Carrying it on you outside the home, or transporting it, is banned without a legitimate reason. The law targets both, carrying and transporting, and not only the knife in your pocket.

That leaves size. The idea that a blade shorter than the palm of your hand escapes the rule is widespread: it appears neither in the service-public.fr fact sheet nor in the ministerial answer. The great families of folding knives are presented in the guide to French pocket knives.

A legitimate reason is not something you can declare for yourself: it is assessed by others. First by law enforcement officers during a check, then by a judge if the matter goes further. The same blade may therefore be seen differently depending on where it is and on the circumstances of the moment.

The official fact sheet cites situations that may amount to a legitimate reason: professional use, an outdoor activity such as fishing or camping, or transporting a knife you have just bought. These are examples, not free passes. Each one remains subject to the same examination of place, circumstances and context.

One reason, on the other hand, is ruled out by the official fact sheet: self-defence. Explaining that you keep a knife to face an assault or a danger is not enough to make it a legitimate reason.

Carrying and transporting are two separate words, but they obey a single condition. The official fact sheet subjects both to the same legitimate reason requirement: a knife out of reach, at the bottom of a bag or a suitcase, does not escape the rule for all that.

The car is no exception. A knife left in the glove box, the door pocket or the boot is being transported, even if nobody touches it during the journey. The reason is assessed according to place, circumstances and context, just as it is anywhere else.

That leaves the sheath. It protects the blade and the hand, and it keeps a knife from travelling bare at the bottom of a bag. It does not create a reason, though: a knife in its sheath is still a knife being carried or transported. At the Résiliant workshop, the sheath, hand-stitched in Thiers from vegetable-tanned leather, is an option chosen at the quote stage; the sheaths are shown on the accessories page.

These figures are ceilings. They set what the law allows a judge to impose, not what is imposed every time. They do, however, say one thing clearly: carrying a knife without a legitimate reason is not a mere formality, it is an offence punishable by imprisonment.

Self-defence comes back here from another angle. Since it is not a legitimate reason, invoking it during a check does not justify the presence of the knife: it is precisely the reason the official fact sheet rules out.

The first text is a ministerial order of 4 July 2025, which sets the list of other weapons classified in category D. Two kinds of knife are named in it. The butterfly knife, or balisong, whose handle is made of two pivoting grips that cover the blade when it is closed. And the lock knife with automatic opening.

The second is decree no. 2025-894 of 5 September 2025, which amends the regulations on bladed weapons. It moves so-called "zombie" knives into category A1, the category of weapons whose acquisition and possession are banned.

The same decree requires businesses selling bladed weapons, including those that sell online, to display the ban on sales to minors. This obligation is a reminder that the freedom to buy a knife applies to adults.

Résiliant knives rest on a different mechanical principle. On all eight of the workshop's models, the blade rises from the top of the handle, driven by the ring through which the index finger passes; no spring pushes it, and opening remains entirely manual. Locking is by a reversed liner lock, with the liner working at the top of the handle. The full gesture is detailed in the article on the reverse-opening knife.

Le Résiliant Tanto, the workshop's first model, was designed as a work tool, worn on the belt on building sites, on roofs or in the workshop. That says what it is for, not what the law makes of it: carrying it, like carrying any knife, remains subject to a legitimate reason assessed case by case.

Only the Mini Tanto, a reduced-size Tanto, is truly a pocket knife. The other models are worn in a sheath on the belt or kept in a display cabinet. Le Résiliant 2.0, in 90MCV8 carbon steel, is intended for the casse-croûte, the French snack break. In every case, the same rule applies as soon as the knife leaves the house.

The workshop ships its knives within France and abroad: its first orders came from Belgium, Switzerland and the United States. Outside France, the French rule no longer applies: a knife obeys the rules of the country where it will be carried, and those rules vary from one country to another. By air, on departure from the European Union, EU aviation security rules ban sharp objects such as knives from the cabin: a knife travels in the hold.

Every Résiliant is ordered on a quote: the model, the steel or damascus and the handle material are chosen with the cutler, and the leather sheath is added as an option.
