Title: Gravity knife
Content:  In some countries, such as the United Kingdom, Canada, and in certain U.S. states, a gravity knife is defined under the law as a prohibited weapon, with attendant criminal penalties. Other laws may criminalize the ownership, sale, importation, or carrying of a gravity knife upon one's person, either concealed or unconcealed. In the United States, some state criminal codes prohibit either the ownership or the carrying of gravity knives, either by name or by including a functional description of their opening mechanisms. Other state criminal codes bar gravity knives by redefining them variously as switchblades or butterfly knives. Local jurisdictions including cities and counties may also restrict the ownership

Occasional disputes over what constitutes a switchblade knife under federal law has occasionally resulted in U.S. Customs seizures of knives from U.S. importers or manufacturers. In one case the seizure of a shipment of Columbia River Knife & Tool knives resulted in an estimated US$1 million loss to the company before the shipment was released. Amendment 1447 to the Switchblade Knife Act (15 U.S.C. §1244), signed into law as part of the FY2010 Homeland Security Appropriations Bill on October 28, 2009, provides that the Act shall not apply to spring-assist or assisted-opening knives (i.e. knives with closure-biased springs that require physical force applied to the blade to assist in opening the knife).
Title: Pocketknife
Content:  over a certain length, particularly when combined with locking blade mechanisms. The possession or carrying of a folding pocketknife with a quick-opening mechanism such as a gravity knife, butterfly knife (balisong), or switchblade may be prohibited. Under U.S. federal law, switchblades and ballistic knives are banned from interstate shipment, sale, or import, or possession on federal or Indian lands or U.S. possessions and may be prohibited entirely in some states. Knives of any size or configuration may be prohibited by federal or state laws in certain designated areas or places, such as schools, courthouses, jails, power plants, or airports. In the United Kingdom it is illegal to carry a folding knife having a blade more than 3 inches 
Title: Knife legislation
Content:  Under the Switchblade Knife Act of 1958 (amended 1986, codified at 15 U.S.C. §§1241–1245), switchblades and ballistic knives are banned from interstate shipment, sale, or importation, or possession within the following: any territory or possession of the United States, i.e. land belonging to the U.S. federal government; Indian lands (as defined in section 1151 of title 18); and areas within the maritime or territorial jurisdiction of the federal government, with the exception of federal, state law enforcement agencies and the military. In addition, federal laws may prohibit the possession or carrying of any knife on certain federal properties such as courthouses or military installations. U.S. federal laws on switchblades do not apply to the possession or sale of switchblade knives within a state's boundaries; 
Title: Shuriken
Content:  Modern shuriken are most often made of stainless steel and are commercially available in many knife shops in Europe and North America, or via the Internet. They are illegal to possess or carry in some countries, such as Belgium, the Netherlands, Canada, Germany, and the United Kingdom (manufacture, sale, distribution and import). In the United States, some states prohibit them (e.g., California, Indiana, New York ) while others allow them. In some cases they may be allowed but are still subject to specific local legislation. Owners may be required to possess a certificate for the possession of knives.
Title: Pocketknife
Content:  Pocketknives are legal to own in most countries, but may face legal restrictions on their use. While pocketknives are almost always designed as tools, they do have the potential to be considered by legal authorities as weapons. In the United States, knives are regulated by federal, state, and municipal laws. Some jurisdictions prohibit the possession or use of pocketknives that feature locking blades. Others prohibit certain blade styles perceived by law enforcement and legal authorities as optimal for offensive fighting, transforming the pocketknife from a utility tool into a deadly weapon. These might include knives with dirk, dagger (double-edge), bowie, or stiletto blades. In some jurisdictions it is illegal to conceal knives larger than a certain size or with 
Title: Knife collecting
Content:  Knife collecting is a hobby which includes seeking, locating, acquiring, organizing, cataloging, displaying, storing, and maintaining knives. Some collectors are generalists, accumulating an assortment of different knives. Others focus on a specialized area of interest, perhaps bayonets, knives from a particular factory, Bowie knives, pocketknives, or handmade custom knives. The knives of collectors may be antiques or even marketed as collectible. Antiques are knives at least 100 years old; collectible knives are of a later vintage than antique, and may even be new. Collectors and dealers may use the word vintage to describe older collectibles. Some knives which were once everyday objects may now be collectible since almost all those once produced have been destroyed or discarded, like certain WW2 era knives made with zinc alloy handles which are rapidly degrading due to the material's shelf life. Some collectors collect only in childhood while others continue to do so throughout their lives and usually modify their collecting goals later in life.

Content:  Additionally, it is illegal to carry a fixed-blade knife with multiple cutting edges. However such a knife may be kept at home for collector purposes.
Title: Gravity knife
Content:  carrying of gravity knives. In a few jurisdictions, such as Colorado and New York City, courts have periodically attempted to classify ordinary lock-blade folding knives with a blade that may be opened by centrifugal force (normally, using a flicking motion of the wrist) as a gravity knife, thus making the knife's owner subject to the same criminal penalties imposed for illegal possession of a gravity knife. The New York statute banning gravity knives has been declared "unconstitutionally vague" by a federal District Court in March 2019. New York State legalized the possession of gravity knives on May 30, 2019 but New York City retains its ban on public transport.

The special exception which exists in the Criminal Justice Act 1988 (Sec. 139) for folding knives (pocket knives with non-locking blades) with a cutting edge (not blade) less than 3 in long, is another "common sense" measure accepting that some small knives are carried for general utility; This exemption
