Task: Question Answering
Input (English): passage: In France, any knife of any blade length with a fixed blade, or a folding blade with a locking system, falls into unregulated Category D weapon (armes de catégorie D en vente libre). Unregulated category D weapons may be legally purchased if over 18 years of age, but they may not be carried on one's person, unless carried ``for good reason'', for example, as part of the tools of one's profession. If carried in a vehicle, such knives must be placed in a secure, locked compartment not accessible to the vehicle occupants. In addition, French law provides that authorities may classify any knife as a prohibited item depending upon circumstances and the discretion of the police or judicial authorities. Since ``reasonable size'' knives are merely tolerated in most circumstances, authorities may summarily confiscate it.
