I was convinced of a (non-violent) crime, it is legal for me to carry a fixed blade knife openly wrapped on the side All knives are legal to own in Virginia. However, you should not hide dangerous weapons such as Bowie knives, switching blades, throwing knives and machetes. Dangerous weapons are prohibited in schools, with the exception of a foldable pocket knife, which is less than 3 inches long. Carrying something bigger than a 3-inch folding ash knife on the school grounds is a crime. Knives are a top choice for hunting, self-defense, and sports weapons, but it`s important to know your state`s knife laws. The patterns have often sat in the gray area of legality, and the specific details of the law can vary from state to state. Hawaii prohibits all switching blades. Balisongs and possession of gravity meters can be a crime. All other types of knives are legal to own and carry. Only knives with ankles are illegal to hide.
There is a zero tolerance policy for knives on school grounds. At the state and local levels, most jurisdictions declare flick knives to be prohibited weapons in their respective laws, codes and regulations. Persons residing in states that do not have specific firearms laws for switching blades (such as Tasmania) are still subject to federal customs legislation, but under conditions where the state has no legislation against these items, an exemption may be requested and obtained if approved by the Chief of Supervision of that state police service. Delaware law provides, under Section 1446, that a « switching blade » is a knife « the blade of which is loosened by a spring-loaded mechanism or by gravity. » Since 1953, it has been illegal in Delaware to sell, offer or possess such a knife. No decision of the state court of appeals dealt with developments in knife technology in the years that followed. It is not possible to predict with certainty whether, for example, knives with a « sustained opening » would be subject to the restriction, although the blade of the typical assisted door opener is not released by a spring-loaded mechanism or by gravity, at least initially. We recommend caution when it comes to knives in this category. In Italy, the switching blade or self-opening knife (coltello a scatto) is generally defined as an arma bianca (offensive weapon) rather than a tool. Although the purchase of adult knives is legal, these knives cannot be transported outside one`s own property or carried on the person, nor concealed or discovered, nor transported in a motor vehicle in which the knife is accessible to the driver or passenger.   The Italian Ministry of the Interior has warned that switching blade knives are considered offensive weapons in their own right.  Under U.S. federal law, since 1958, switch blades have been illegally imported from abroad or purchased through interstate commerce under the former Switchblade Knife Act (15 U.S.C.
§§§§1241-1245). In recent years, many U.S. states have repealed laws prohibiting the purchase or possession of automatic or switching blade knives in their entirety. In Sweden, the possession of knives in a public place, at school or on public roads is prohibited.  Exceptions apply to persons who carry knives for professional or otherwise justified reasons. Switching blades may not belong to anyone under the age of 21.  If you are over the age of 18 in Mississippi and have not committed any crime, you can legally possess any knife. Convicted criminals and persons under the age of 18 may not possess switching blades, Bowie knives or butcher`s knives. The secret carrying of dangerous weapons is prohibited and knives are not allowed near schools. Most knives are legal in Vermont, with the exception of switching blades, which have a blade of 3 inches or more.
Knives cannot be transported on or near school property. Knives can be carried hidden as long as you do not wear them with the intention of injuring another person. The switching blades date from the mid-18th century.  The development of the first automatic knife was made possible by the invention of small temperature-controlled springs by watchmaker Benjamin Huntsman in 1742.  In the United States, the commercial development of the switching blade knife was dominated primarily by the inventions of George Schrade and his New York Press Button Knife Company, although W.R. Case, Union Cutlery, Camillus Cutlery, and other American knife manufacturers also marketed automatic knives of their own design.  Most of Schrade`s blade models were automatic versions of utility-oriented jack knives and pocket knives, as well as smaller pocket knife models designed to appeal to buyers. In 1903, Schrade sold his shares in the New York Press Button Knife Co. to the Walden Knife Co. and moved to Walden, New York, where he opened a new factory.   There, Schrade became the company`s production manager and established a production line to produce various samples of schrade-designed switching blade knives, ranging from a large folding hunter to a small pocket knife.
 Walden Knife Co. has sold thousands of copies of Schrade`s original Bolster button design.   The Switchblade`s negative public reputation as a tool of the juvenile offender, derived from sensational media coverage of the 1950s, has been enshrined in the penal codes of many states, and some of these laws persist to this day. Thus, in some States, the possession or carrying of an auto-opening knife or switch blade may become illegal in certain circumstances solely because of its aesthetic design or appearance, or simply because of its use as a weapon.    For example, switched blade knives whose blade shape was originally designed to stab or push, such as Dirk, Dolch, Dagger or Stiletto, are automatically considered « lethal weapons » (i.e., knives designed or specially adapted to be used as a weapon to inflict death or serious bodily injury).  It is legal to wear karambits in Delaware. Under Delaware law, a knife with a blade not exceeding three inches is legal to carry. Karambit Knife meets the criteria and is therefore legal in Delaware. Automatic or shift knives have been manufactured in the following countries: Argentina, China, Czech Republic, England, France, Germany, Hong Kong, India, Italy, Japan, Mexico, Korea, Pakistan, Poland, Russia, Spain, Switzerland, Taiwan and the United States. [Citation needed] Under Delaware`s federal knife law, it is illegal to sell lethal weapons and knives to minors under the age of 18. A minor may not purchase any type of knife or blade without the consent of his or her parents or guardians.
Together with former Challenge employees, Schrade founded a second company, the Geo. Schrade Knife Company, primarily to manufacture its Presto series of switching knives. In 1937, Schrade launched two other low-cost switching blade knives designed to appeal to young people, the Flying Jack and the Pull-Ball Knife.  The Flying Jack had a sliding control lock and could be manufactured with one or more self-opening blades. The pull ball opened by firing a bullet that was at the back of the handle.  Schrade then made alternative configurations to the ball handle, including cubes, rings, eight balls, or different colors.  Unfortunately, the pull ball required two hands to open, eliminating much of the use of the Switchblade as a one-handed knife.  Since the blade capture mechanism required a lot of space in the handle, the length of the knife blade was short compared to the length of its handle.  Schrade manufactured numerous traction ball knives sold under other brands, including Remington, Case, and the J.C.N. Co. (Jewelry Cutlery Novelty Company of North Attleboro, Massachusetts)  Always looking for a new way of approaching customers, Schrade experimented with new forms of circuit blade designs until his death in 1940. The company`s application was approved by the United States.
Army Materiel Command in December 1940 as Knife, Pocket, M2.  The M2 had a 3.125-inch clippoint blade and a carrying handle. Aside from the bail, the M2 was in every way a copy of George Schrade`s popular civilian Presto safety button model. The M-2 was distributed primarily to U.S. Army paratroopers during the war, although some knives were apparently distributed to crews and members of the Bureau of Strategic Services. When delivered to paratroopers, the M2 was usually worn in the knife pocket with two zippers on the upper chest of the M42 jump uniform jacket. After the war, the M2 was manufactured by Schrade (now Schrade-Walden, Inc.) as a paratrooper blade knife (MIL-K-10043) under a post-war military contract. In addition, other companies such as the Colonial Knife Co. produced civilian versions of the M2 after the war.
Update 08/2022 Switchblades, Automatic and OTF knives are now legal in 40 states. See the graph below. This makes it really questionable for the many people who buy a new box of large kitchen knives and want to take it home in their car. Hmm. According to Article 1446 of the 11 Dei.C, it is illegal to sell, buy and transport circuit sheets with a blade that can be easily opened by a spring mechanism or by gravity. The design of such knives usually allows a person to perform offensive activities with an unclassified offense. From 1923 to 1951, Union Cutlery Co. of Olean, New York, produced a series of lever switching blades designed for the mid and upper ends of the market, with celluloid, deer or shaken bone handles, a push button mounted on a bolster, all with the company`s KA-BAR brand on the blade.
 The range included KA-BAR Grizzly, KA-BAR Baby Grizzly and KA-BAR Model 6110 Lever Release knives.  The largest model was KA-BAR Grizzly, a foldable hunter pattern with a wide Bowie-shaped clip tip blade.
