Section 3(1) of the Weapons Act 2006 lists knives with a stop notch and a gushing blade as a prohibited weapon.  In Belgium, police and local courts are also allowed to prohibit the carrying or possession of a large number of knives that are not expressly prohibited by law, if the owner cannot prove a legitimate reason for possession of the knife, especially in urban areas or at public events.   The first spring-loaded switch blade that could be authenticated appeared in the late 1700s, probably built by a craftsman in Italy.  After 1816, automatic knives were not produced in Italy for 50 years due to the laws of the Austro-Hungarian Empire.  By 1900, Italy had resumed production of automatic needle knives, all handmade by individual cutlers or small cutlers. Most of these cutlers were concentrated in the towns of Maniago, Frosolone, Campobasso and Scarperia. Since the Austrian Weapons Act of 1996, switch blades, like all other knives, are generally legal to buy, import, possess or carry, regardless of the length of the blade or the opening or locking mechanism.  The only exceptions are minors (defined as persons under the age of 18) and persons who have been expressly prohibited from possessing and carrying weapons: both groups may only possess knives that are not considered “weapons” under the Weapons Act, defined as “objects which, by their nature, are intended to reduce or eliminate a person`s ability to defend himself or herself by direct impact”.
 Switching blades generally fall under this definition.  The three most common types of knives – switched knives, folding knives, and fixed-blade knives (also known as dirks and daggers) – have certain rules and are explained in more detail below. The open carrying law states that the handle or handle of a knife cannot be hidden (or hidden), even by clothing or the sheath of the knife. This law exists to ensure that anyone in the vicinity of the person carrying the knife can see it clearly to avoid surprise attacks. A fixed blade knife is a knife without a folding mechanism. A kitchen knife is a common example. Ice axes and other items can also be included in this category. In California law terms, the words “dirk” and “dagger” mean the same thing: a knife that can easily be used as a dagger weapon. In California, dirks, daggers and other sheath knives must be worn openly and must not be hidden. In the late 1930s, the German Luftwaffe began training a paratrooper or paratrooper and, as part of this effort, developed special equipment for the airborne soldier, including the paratrooper knife, which used a gravity-operated mechanism to unfold its soaring spearhead blade from the handle. The German paratrooper knife, which had a point of marlin, in addition to the sharp blade, was used to cut the rigging and loosen the lines, although it could be used as a weapon in an emergency.
In 1940, the U.S. Army commissioned the Geo. Schrade Knife Co. to produce a small, single-edged switch blade for U.S. airborne troops, which would be used in the same way as parachute knives.  The knife was not primarily intended as a combat knife, but as an aid to allow a paratrooper to quickly cut himself out of his lines and harness if he could not escape after landing. The 12022 PC Penal Code states that in addition to the sentence you are sentenced to for illegal possession of a knife, you can receive a 1-year sentence increase in the state prison. This increase in punishment cannot be added to the penalties for throwing a weapon or attacking with a lethal weapon.
Any type of self-opening knife or blade tool that can be opened with one hand (including any one-handed knife that has been deactivated by removing the opening mechanism) is illegal to possess or possess. Multi-tool tools with one-handed blades are also illegal to own or own. Manually opened one-handed knives are legal.  After 1945, American soldiers returning from Europe brought with them individually purchased Italian-style copies of needleblades made in Maniago and other cutlery towns.  Although undeniably limited in practicality, the style and beauty of the so-called needle blade was a revelation to American buyers accustomed to the utilitarian nature of most US-made automatic knives, such as the Schrade Presto pocket knife.  Consumer demand for more of these knives has resulted in the importation of a large number of telescopic and side-opening blades, primarily from Italy. In the case of the Switchblade, the name Stiletto derives from the blade`s design, as most Italian designs included a long, thin blade that tapered to a needle-like tip, as well as a thin handle and stunted cross guard reminiscent of the medieval weapon. Most of these needlestick blades used a now iconic thin bayonet blade with a single sword edge and an opposite false edge. Other types of blades were the double-edged dagger and the curved Kris. Some were slim souvenirs for tourists or novelty buyers, while others were made with solid materials and workmanship.
  Finally, several thousand Italian switch blades were exported to the United States. At that time, the traditional Italian method of triggering picklocks was largely replaced by the tilting cheek mechanism, ending the “golden age” of handmade Italian switch blades.  In Italy, the switch blade or knife with automatic opening (coltello a scatto) is generally defined as arma bianca (assault weapon) and not as a tool. Although the purchase is legal for adults, these knives cannot be carried outside one`s own property or carried on the person, neither hidden nor discovered, nor be transported in a motor vehicle in which the knife is accessible to the driver or passengers.   The Italian Interior Ministry has warned that Switchblade knives are considered offensive weapons in their own right.  The first category refers to “Dirks and Daggers”, which can be used as dagger weapons. And there is no blade folding mechanism. Examples of these knives are kitchen knives, ice axes and other fixed blade knives.
Although a person can openly carry these knives in public in a scabbard, it is illegal for a party to carry hidden knives on them. Folding knives are knives that open by pressing on the blade(s) of the knife and have a mechanism that resists when the blade is opened. These include a “pocket knife” or “Swiss Army knife”, a cutter or an “all-purpose knife” According to Section 17235 of the California Penal Code, all folding knives are legal in the state and can be hidden as long as they are in the folded position. There is also no limit to the length of the blade of a folding knife. Under U.S. federal law, since 1958, under the former Switched Blade Knives Act (15 U.S.C. §§1241-1245), it is illegal to import switching blades from abroad or to purchase them through interstate trade. In recent years, many U.S.
states have repealed laws prohibiting the purchase or possession of automatic or switch-blade knives in their entirety. Butterfly knives (also known as Balisong knives) are considered switch blades in California. Other names for switch blades are ejection knives or push-button knives.10 Butterfly knife laws are not specifically detailed in California laws.
