The last point is very important if you carry a knife (allowed) with you. The question you may ask yourself is: is it reasonable and explainable to have a knife available in the current situation? If you`re not sure of the answer, that`s clear. It`s best to store your knife in a place where you may not have it immediately available. Carrying a knife in the Netherlands is a matter of context.

Since 1959, Parliament has passed a number of increasingly restrictive laws and regulations concerning the possession and use of knives and blade tools.

Article 2 „Law on Arms and Ammunition”. lists different types of weapons.  It states: „Melee weapons, percussion rings, daggers, kama, swords, bayonets and other objects whose main purpose is insult” are considered weapons. Most knives are therefore considered tools and are technically legal to own and carry. However, since any knife can be used as a melee weapon and the law does not distinguish between certain types, it is up to the authorities to determine the intent of the person in possession of the knife and whether there is a „good reason” for it. Therefore, knives with a solid blade are considered suitable for certain professions or in hunting and fishing, but are likely to be treated as a weapon in an urban environment. Switch blades, butterfly knives, blades hidden in everyday objects are usually treated as weapons, and pocket knives for opening can also fall into this category. The appearance of the knife (how aggressive it looks), the length (although there is no legal limit to length), where it was worn (large gatherings, schools, public buildings, etc.) and the behavior of the person carrying the knife all play a role in deciding whether the law has been broken. The purchase, possession and carrying of a melee weapon is considered an offence punishable by a fine of up to RSD 10,000 or imprisonment for up to 60 days („Weapons and Ammunition Act”, section 35). 53] In practice, the less like a weapon, the knife looks like a weapon, and if it is carried and used with „good judgment”, the likelihood of legal consequences decreases.
