Knife carry law in Spain

Spain bans automatic knives, daggers (double-edged, under 11 cm) and non-automatic folders with a blade over 11 cm. Other knives are weapons you may not carry outside home or work without need; police judge that need. A reform of the weapons regulation is being fast-tracked, but its knife content is not published.

This summary rests on mostly official, partly secondary sources. Open questions are listed at the end. Treat anything marked unclear as a reason to leave the item at home.

How we apply the law

Rules are checked from the top. The first one that fits decides. Every verdict on this site comes from this list, not from hand typed cells.

1ProhibitedA folding knife or a multitool, automatic
Automatic knives ('navajas automáticas') are prohibited weapons: manufacture, import, sale, possession and use are banned. Possession can be a crime (CP art. 563); carrying is at least a serious administrative offence.
Source
2UnclearA folding knife or a multitool, spring assisted or gravity or flick opening
Spring-assisted, flick and butterfly knives are not named in the Reglamento. Whether they count as 'automáticas' or 'puñales' is not settled in sources read; some lawyers say prohibited. Treat as high risk.
Source
3ProhibitedAny knife or tool, double edged, blade up to 110 mm
Pointed double-edged blades under 11 cm count as 'puñales' and are prohibited weapons. 'Puñales de cualquier clase' are also listed, so longer daggers are also at risk.
Source
4UnclearAny knife or tool, double edged, blade at least 110.1 mm
The Reglamento bans 'puñales de cualquier clase' but defines puñal only for blades under 11 cm. Longer double-edged blades (daggers) are very likely treated as prohibited; no clear text or case found.
Source
5ProhibitedA folding knife or a multitool, two hand opening or one hand manual opening, blade at least 110.1 mm
Non-automatic folding knives (navajas) with a blade over 11 cm, measured from the handle stop to the tip, are prohibited to sell, own and use, except at home as decoration or for collections.
Source
6Reason neededA folding knife or a multitool, two hand opening or one hand manual opening, single edged, blade up to 110 mm
Not a prohibited weapon, but it is a category 5 'arma blanca': carrying outside home, work or sport is banned unless you have a need that police accept. Pointed blades are singled out. Local fines are likely without a clear purpose.
Source
7Reason neededA fixed blade, single edged
Fixed-blade knives are not 'navajas', so the 11 cm navaja ban does not apply, but art. 146 still bars carrying them outside home, work or sport unless there is a real need that agents accept.
Source
8UnclearScissors only or a keychain tool
Not addressed specifically. Anything with a cutting or piercing blade is an 'arma blanca' under art. 2; tiny non-pointed tools are rarely enforced against but no official statement was found.
Source
9UnclearAnything else
Catch-all: combination not covered. Automatic knives, daggers and non-automatic folders over 11 cm are prohibited; everything else requires a need to carry under art. 146.

Specifications come from the makers. Where a maker does not publish the cutting edge length, a length rule can only be answered if even the full blade length falls on one side of the line. Otherwise the result is unclear, on purpose.

What the verdict does not cover

Public transport and restricted zones: Art. 146.2 says it should generally be considered unlawful for people attending public establishments and places of gathering, recreation or entertainment to carry or use weapons. Armed attendance at public assemblies is reported to the court (art. 148.3). Regional and local rules (e.g. Basque Country, Catalonia) were not checked.
Schools, workplaces and events: Not verified beyond art. 146.2 (public venues and gatherings).
In a vehicle: No specific vehicle rule found. Art. 146 applies to carrying outside home, work or sport; police can check people and vehicles to stop illegal carrying (LO 4/2015 art. 18, Reglamento art. 148). Whether a knife stowed in a car trunk counts as carrying was not verified.
Age limits: No minimum age for carrying found; the Reglamento's age rules for buying weapons were not checked.
Buying and importing: Selling, advertising and possession of prohibited knives are banned, including imports. Non-automatic navajas over 11 cm may only be kept at home as ornament/collection. Online purchase and import of ordinary knives by tourists were not verified.
Penalties: Prohibited weapons: possession can be a crime, prison 1-3 years (CP art. 563); administrative carrying of prohibited weapons is a serious infraction with a fine of €601-30,000 (LO 4/2015 arts. 36.10, 39). For non-prohibited blades carried against art. 146, Reglamento art. 156 j) still lists a fine of €300.51 to €601.01 plus seizure; how that old schedule sits beside LO 4/2015 was not resolved. Weapons are seized.
Recent changes: No change to the Reglamento's knife rules found in force. Last consolidated Reglamento update shown by BOE: 4 Apr 2025. A PP motion calling for more banned knife types was reported approved by Congress (BOCG 30 Apr 2026, only seen in a search excerpt). The Interior Minister promised in April 2026 to push measures on knives in public spaces, and Interior and the Basque government agreed on 8 Jul 2026 to promote a Reglamento change.
Pending changes: 13 Oct 2026: the Council of Ministers authorised urgent processing of a royal decree amending the Reglamento de Armas (La Moncloa reference list, primary). The published agenda gives no content. Industry sources describe a broad reform (licences, EU directive), and Basque officials want a ban on carrying knives in crowded places; whether this decree contains any knife rule is NOT confirmed. Expect a draft within 1 to 3 months.

Reasons the authorities have accepted

Art. 146 gives no list; agents judge 'necesidad' by occasion, time and circumstance. Plausible examples (not official): hunting, fishing or camping trip, work or trade use. Not verified by a source.
