Editing Switchblade (section)

==Legality==

===Austria===
Beginning with the Austrian Arms Act of 1996<ref>Waffengesetz (1996): The 1996 version of the ''Waffengesetz'' appears to drop the switchblade from the category of prohibited weapons entirely, regardless of blade type: "Gegenüber der bisherigen Rechtslage sind nunmehr Waffen, mit denen ohne Verwendung von Patronen reizauslösende Mittel versprüht werden können, sowie Spring- und Fallmesser nicht mehr der Kategorie der verbotenen Waffen zuzurechnen&nbsp;... Im Hinblick auf andere ebenso gefährliche Stichwaffen (z.B. Butterflymesser) und die Tatsache, dass Spring- und Fallmesser in den übrigen EU-Mitgliedstaaten keineswegs verboten sind und daher von Touristen und anderen Reisenden, in Unkenntnis des österreichischen Waffengesetzes, mitgebracht werden, ließ es zweckmäßig erscheinen, auch diese Waffen aus der Liste der verbotenen zu streichen."</ref> switchblades, like all other knives, are generally legal to buy, import, possess or carry, regardless of blade length or opening or locking mechanism.<ref name="Waffengesetz 1996">Waffengesetz (1996)</ref> The only exception are minors (defined as persons under the age of 18) and people who have been expressly banned from owning and carrying any weapon (''Waffenverbot''): both groups may only possess knives which are not considered "weapons" under the Arms Act, defined as "objects that by their very nature are intended to reduce or eliminate the defensive ability of a person through direct impact".<ref name="Waffengesetz 1996"/> Switchblades usually fall under that definition.<ref name="Waffengesetz 1996"/>

In Austria the regulatory laws of individual states and the Assembly Act prohibit switchblades and other knives from being carried into a public building, school, public assembly, or public event.<ref>Jell, Sonja (Magistra) ''[http://www.messer-portal.com/basiswissen/messerwissen/messer-und-reisen/waffengesetz-messer-in-oesterreich Weapons Law: Knives in Austria]''</ref>

===Australia===
In Australia, switchblades are banned by the Customs (Prohibited Imports) Regulations as a Prohibited Import. Australian customs refer to the automatic knife or switchblade as a flick knife. Australian law defines a flick knife as a knife that has a blade which opens automatically by gravity, by centrifugal force, or by any pressure applied to a button, spring or device in or attached to the handle of the knife, a definition that would cover not only switchblades and automatic-opening knives, but also [[Gravity knife|gravity knive]]s and [[Butterfly knife|balisong]]s.

At a state and local level, most jurisdictions declare flick knives to be prohibited weapons in their respective acts, codes and regulations. Persons residing in states that do not have specific weapons legislation covering switchblades (such as [[Tasmania]]) are still covered by Federal Customs legislation, but in conditions where the state has no legislation against such items, an exemption may be applied for and received if approved by the chief supervisory officer of the police service in that state.

Some states which have specific legislation against switchblades allow individuals to apply for an exemption from this legislation if they have a legitimate reason. For example, in the state of Victoria, a member of a ''bona fide'' knife-collectors' association, who is not a prohibited person (per the Firearms Act 1996), and meets other guidelines and conditions may apply to the Chief Commissioner of Police for a Prohibited Weapons Exemption to possess, carry, or otherwise own such a knife. This exemption may then, in turn, be used to apply to the Australian Customs Service for an import permit.<ref>{{cite web|url=http://www.customs.gov.au/site/page.cfm?u=4369#e1066|title=Australian Government Department of Immigration and Border Protection|website=www.customs.gov.au}}</ref>

===Canada===
Under Part III of the [[Criminal Code (Canada)|Criminal Code]] a knife that has a blade that opens automatically by gravity or centrifugal force or by hand pressure applied to a button, spring or other device in or attached to the handle of the knife, is illegal to possess, import, sell, buy, trade, or carry on one's person. These are prohibited weapons (''armes défendues'').<ref>Pyzer, Jonathan, ''Possession of Prohibited Weapons- Pepper Spray/Nunchucks/ Switchblades'', [https://www.torontodefencelawyers.com/possession-prohibited-weapons-pepper-spraynunchucks-switchblades/], 16 January 2021, retrieved 28 March 2022:  Canada Criminal Code SOR/98-462, sections 84(1) and 94(3): "It is a criminal offence under Canadian law to possess any of the weapons listed in section s. 84(1) and the associated regulations.

===Germany===
The switchblade is known in Germany as the ''Springmesser'' (also called a ''Sprenger''<ref name="BE">Benson, Ragnar (1989). ''Switchblade: The Ace of Blades''.

All large side-opening switchblade knives (blade longer than {{convert|8.5|cm|abbr=on}}), [[OTF Knife|OTF switchblades]], balisongs or butterfly knives (blade longer than {{convert|4|cm|abbr=on}}), and gravity knives are illegal to own, import or export under German law. Side-opening switchblade knives with single-edged blades not longer than {{convert|8.5|cm|abbr=on}} and incorporating a continuous [[Knife#Materials and construction|spine]] are legal to own. Legal switchblades may be carried both open and concealed on one's person if there is a justified need for it ("berechtigtes Bedürfnis") or if the weapon cannot be accessed with less than 3 moves ("Transport in verschlossenem Behältnis"). Other laws or regulations may still prohibit the carrying of otherwise legal automatic or switchblade knives, particularly in certain situations or places (gatherings on public ground, check-in areas of airports).

===Hungary===
According to [[decree]] 175/2003. (X. 28.) of the [[Hungarian government]] ''a közbiztonságra különösen veszélyes eszközökről'' (about the instruments particularly hazardous to public safety), it is prohibited to possess a switchblade in public places or private places open to the public – that includes the inside of vehicles present there – and on public transport vehicles, except for filmmaking and theatrical performances. Members of the [[Hungarian Army]], law enforcement, national security agencies and armed forces stationed in Hungary are exempt from this limitation together with those who are authorised to carry such instruments by legislation. Sale of a switchblade is authorised only to the persons and organizations above. [[Customs clearance]] of switchblades may not be performed for private individuals such as tourists.

===Hong Kong===
According to the Weapons Ordinance (Cap. 217), any person who has possession of any prohibited items (including Gravity Knife and Flick Knife) commits an offence.<ref>{{Cite Hong Kong ordinance|name=Weapons Ordinance|217|4|text=§ 4, also refer to the Schedule}}</ref>

===Italy===
In Italy, the switchblade or automatic opening knife (''coltello a scatto'') is defined by law as an offensive weapon (''arma bianca'') rather than a tool. A firearms license (''porto d'armi'') or a police clearance (''nulla osta'') are required to legally purchase one. Such knives may not be transported outside of one's property without a valid reason (self-defense is not) and it is always illegal to carry one in a ready to use condition, neither concealed nor unconcealed.<ref>Articolo 699 ''Codice Penale'', ARMI - Porto Abusivo</ref><ref>''[http://www.avvocati.ud.it/public/rivista_on_line/art567.html Definizione Di Arma Impropria: Coltello a Scatto] {{Webarchive|url=https://web.archive.org/web/20120929000028/http://www.avvocati.ud.it/public/rivista_on_line/art567.html |date=2012-09-29 }}'', Tribunale di Gorizia, Sezione penale, 20 May 2009</ref> The Italian [[Ministry of Interior (Italy)|Ministry of Interior]] has warned that switchblade knives will be considered offensive weapons in their own right.<ref>Si segnala che con circolare ''559C.7572.10179(17) 1'' il Ministero dell'Interno ha avvertito che i coltelli a scatto sono da considerare armi proprie, con tutte le conseguenze in ordine al loro regime giuridico.</ref>

===Russia===
In Russia, switchblades ([[Russian language|rus.]] ''автоматический нож'', ''выкидной нож'', ''пружинный нож'') are illegal only if their blade's length is more than {{convert|9|cm|in|abbr=on}} – this is an [[Crime|illegal]] weapon, and there is a [[fine (penalty)|fine]] 500–2000 Russian [[ruble]]s (about $8–30) and [[confiscation|withdrawing]] of the knife only for carrying it (article 20.8 of [[Offences Code of Russia]]), but not for illegal purchasing and possession (keeping at home or somewhere else). Only self-making and selling white arms (rus. ''холодное оружие'') is a [[crime]] in Russia (these two crimes are punished by: part 4 article 222 and part 4 article 223 of [[Russian Criminal Code]]). If the blade is shorter than 9 centimetres, anyone (even if people younger than 18 years old, having a [[criminal history]] or [[mental illness]]) can buy, own and [[concealed carry]] ([[open carry]] of any weapon or things that look like weapon at [[human settlement]]s is forbidden in Russia; with the exception for [[policeman|policemen]]) such a switchblade without any [[license]]. But even in this case, it is recommended that people carry on their person an official certificate ([[type approval]]) (which is usually in a box with a purchased knife), which proves that it is not a melee weapon and not restricted to carry, in which case even knives longer than 9&nbsp;cm are sometimes approved.<ref>{{cite web|url=http://zakonprost.ru/zakony/ob-oruzhii/statja-6/|title=Статья 6 ограничения устанавливаемые на оборот гражданского и служебного оружия федеральный закон об оружии n 150-ФЗ (скачать) (2017).

Indeed, much of the language in the Restriction of Offensive Weapons Act 1959 appears to be taken directly from the American law.

==== Federal law ====
The ''Switchblade Knife Act'' ({{USPL|85|623}}, {{USStat|72|562}}, aka ''SWA'', enacted on August 12, 1958, and codified in {{USC|15|1241|1245}}) prohibits the manufacture, importation, distribution, transportation, and sale of switchblade knives in commercial transactions [[Commerce Clause|substantially affecting interstate commerce]]<ref>In ''Gibbons v. Ogden'', the U.S. Supreme Court first established the principle that Congress may regulate under the [[Commerce Clause]] of the Constitution only those activities within a state that arise out of or are connected with a commercial transaction, which viewed in the aggregate, substantially affect interstate commerce.</ref> between any state, territory, possession of the United States, or the District of Columbia, and any place outside that state, territory, U.S. possession, or the District of Columbia. The Act also prohibits possession of such knives on federal or Indian lands or on lands subject to federal jurisdiction. The federal SWA does ''not'' prohibit the ownership or carrying of automatic knives or switchblades inside state lines while not on federal property, nor does it prohibit the acquisition or disposition of such knives in  an intrastate (in-state) transaction.  Finally, the law does not prohibit interstate knife sales or transactions that are either noncommercial in nature, or which do not substantially affect interstate commerce (as defined by recent decisions of the U.S. Supreme Court).

U.S. Code Title 15, Sect. 1241 defines switchblade knives as any knives which open "1) by hand pressure applied to a button or other device in the handle of the knife, or any knife having a blade which opens automatically; (2) by operation of inertia, gravity, or both". The Act also prohibits the manufacture, sale, or possession of switchblade knives on any Federal lands, Native American reservations, military bases, and Federal maritime or territorial jurisdictions including the District of Columbia, Puerto Rico, and other territories.<ref name="Walker">Walker, Greg (1993). ''Battle Blades: A Professional's Guide to Combat/Fighting Knives'' (Hardcover), pages 210 {{ISBN|0-87364-732-7}}</ref><ref>Title 15, Ch. 29, § 1241 United States Code (Definitions): The term “interstate commerce” means commerce between any State, Territory, possession of the United States, or the District of Columbia, and any place outside thereof.</ref> The act was amended in 1986 to also prohibit the importation, sale, manufacture, or possession of [[Ballistic knife|ballistic knives]] in interstate commerce.

U.S.C. 1716 prohibits the mailing or transport of switchblades or automatic knives through the U.S. mails ([[U.S. Postal Service]]), with a few designated exceptions.<ref name="Walker"/> The act provides for a fine and/or imprisonment of not more than one year.<ref name="Walker"/> {{USC|18|1716(g)(2)}} provides:

{{USC|15|1244}} provides that the federal ''Switchblade Knife Act'' does '''not''' apply to: 1) any common carrier or contract carrier, with respect to any switchblade knife shipped, transported, or delivered for shipment in interstate commerce in the ordinary course of business; 2) the manufacture, sale, transportation, distribution, possession, or introduction into interstate commerce of switchblade knives pursuant to contract with the Armed Forces; 3) to the Armed Forces or any member or employee thereof acting in the performance of his duty; 4) the possession and transportation upon his person of any switchblade knife with a blade {{convert|3|in|cm|abbr=on}} or less in length by any individual who has only one arm, and 5) a knife "that contains a spring, detent, or other mechanism designed to create a bias toward closure of the blade and that requires exertion applied to the blade by hand, wrist, or arm to overcome the bias toward closure to assist in opening the knife".<ref name="Walker"/>

====State laws====
In addition to federal law, some U.S. states have laws restricting or prohibiting automatic knives or switchblades, sometimes as part of a catchall category of ''deadly weapons'' or ''prohibited weapons''. A few states, among them Delaware, Hawaii, New Jersey, New Mexico, and New York, prohibit sale, transfer, ownership or possession of automatic knives or switchblades as deadly or prohibited weapons, while others such as New Hampshire and Arizona have no restrictions on sale, ownership, possession, or carry (with some location-specific exceptions). Other states allow purchase, possession, and carrying on one's person to a limited degree, sometimes with restrictions on blade length or location.

The negative public reputation of the switchblade as the tool of the juvenile delinquent, derived from sensational media coverage of the 1950s, was enshrined in many states' criminal codes, and some of these laws persist to this day.  Thus in some states, the possession or carrying of an automatic-opening knife or switchblade may become illegal based solely on its design or aesthetic appearance, or simply its use as a weapon in a given circumstance.<ref name="ReferenceC">New Jersey Code of Criminal Justice – 2C:39-3e, 39-3g(2), 39-5</ref><ref name="See 2017">See ''State of New Jersey v. Montalvo'', 162 A.3d 270 (2017)</ref><ref name="akti.org">American Knife & Tool Institute, ''New Jersey Knife Laws At A Glance'', akti.org, retrieved 22 March 2022 [https://www.akti.org/state-knife-laws/new-jersey]</ref>  For example, switchblade knives with blade shapes originally designed for the purpose of stabbing or thrusting, such as the [[dirk]], [[dagger]], [[poignard]], or stiletto are automatically considered to be 'deadly weapons' (i.e. knives designed or specially adapted for use as a weapon to inflict death or serious bodily injury).<ref name="ReferenceD">American Knife & Tool Institute, ''California Knife Laws At A Glance'', akti.org, retrieved 22 March 2022 [https://www.akti.org/state-knife-laws/california]</ref>

Over the years, state judicial decisions have expanded the original reach  of switchblade laws, either by reclassifying single-edged automatic pocket knives with short, general-purpose blades as illegal 'dirks or daggers', or by re-defining otherwise legal manually-operated lock-blade pocket knives as a prohibited gravity knife, flick knife, or switchblade.<ref name="ReferenceD"/><ref>''People v. Hester'', 58 Cal.App.5th 630 (2020): In People v. Hester, a state appeals court went so far as to define an ordinary ''[[boxcutter]]'' utility knife with an exposed blade length of less than {{convert|1|in|cm|abbr=on}} as a 'dirk or dagger' under the California Penal Code</ref><ref>KnifeRights.org, ''UPDATE: Motion for Reargument in NY Assisted-Opener = Switchblade Case Denied'', October 28, 2018 retrieved 22 March 2022 [https://kniferights.org/legislative-update/motion-for-reargument-filed-in-ny-assisted-opener-case-knife-rights-helps-defendant-who-had-ineffective-counsel/motion-for-reargument-in-ny-assisted-opener-switchblade-case-denied]</ref>  Persons who used knives deemed prohibited as in their work or for self-defense, or who could not afford adequate legal representation, particularly racial minorities, have been disproportionately affected by the capricious enforcement of such laws.<ref>Comstock, Paul, ''Knife laws: Companion bills Seek State Preemption of Municipal Ordinances'', The Columbus Dispatch, 26 April 2021 [https://www.dispatch.com/story/news/local/2021/04/26/knife-laws-companion-bills-seek-state-preemption-municipal-ordinances/7390605002] retrieved 22 March 2022</ref>

In response to complaints raised about the constitutionality and inconsistent application of existing statutes to modern knife designs, several states such as Alaska, Arkansas, Indiana, Kansas, Michigan, Missouri, Montana, Tennessee, Texas, Virginia, West Virginia, and Wisconsin have repealed older laws against possession or purchase of switchblade or automatic knives. Five states still prohibit anyone from selling, purchasing, owning or carrying a switchblade.

In August 2024, the [[Massachusetts Supreme Judicial Court]] relied on the 2022 U.S. Supreme Court decision ''[[New York State Rifle & Pistol Association, Inc. v. Bruen]]'' when it struck down a 1957 ban on [[switchblade]] knives in the state, on the grounds there were no similar bans at the time of the writing of the Second and Fourteenth Amendments.<ref name="Ellement">{{cite news |url=https://www.bostonglobe.com/2024/08/27/metro/sjc-rules-switchblade-knife-possession-not-a-crime/ |newspaper=[[The Boston Globe]] |title=Mass. high court rules possessing a switchblade knife is no longer a crime under the Second Amendment |author=John R.
