The constant emergence of new models of knives, such as opening knives, can complicate questions of legality, especially if state laws have not been carefully designed to clearly define the new model and how to classify it in existing law. This omission has led to cases in the past where state courts have replaced their own understanding of knife design to interpret legislator`s intent when enforcing laws criminalizing certain types of knives. [91] [122] There is no length limit in the Penal Code for carrying knives, but it is prohibited to carry a knife if the owner intends to carry for a purpose dangerous to the peace or to commit a crime. [18] The Bolo knife has a long, heavy blade that curves at the end, making this type of knife one of the most illegal knives in the UK. Any blade curvature or blade length greater than three inches is considered a lethal weapon in the UK and cannot be carried. There is no law prohibiting the carrying of sleeved knives, knives that open both hands, and fixed-blade knives, and certain folding knives not prohibited in public, provided they are not worn for self-defence purposes. [ref. needed] Under the Weapons Act 1996, it is illegal to purchase, import, possess or carry weapons disguised as other objects or goods (e.g. sword sticks or knives disguised as ink pens, brush handles or belt buckles). [2] For regular knives, however, there are no restrictions or prohibitions due to the length of the blade or the opening or locking mechanism.

[3] This is one of my favorite illegal knives in the British Army knife. Trench knives have a long or double-sided blade with a “brass peg” type handle. These knives were developed for attack and trench warfare during World War I. Trench knives are banned in the UK and it is a crime to transport, buy or sell. Our throwing knives and tomahawks have blunt edges, but could be interpreted as sharp objects. Therefore, I would like to suggest that when you use it at home, on your own private property, in appropriate security conditions, you are not violating this law. The German Knives Act defines three categories of knives: (1) prohibited knives; 2) knives called sharp and pushing weapons; and (3) other knives. Some knives are further classified as restricted because they can be owned at home or in the store, but cannot be worn on the person. [28] In addition, Section 42(5) of the Weapons Act gives each German Land the power to enact local regulations in certain areas prohibiting the carrying of weapons “and dangerous objects” in so-called “no-weapon zones” to protect public safety and order. [28] In Berlin and Hamburg, “no-gun zones” have been published. [28] Butterfly knives, also known as “Balisongs,” contain a blade hidden in a split handle. Butterfly knives are illegal in the UK as they can be used as a weapon to injure or even kill someone.

The hidden blade is the main feature of butterfly knives, making it one of the illegal knives in the UK. Many current state penal codes that restrict the use and possession of knives have been amended several times over the years, rather than being rewritten to remove old classifications and definitions that are largely a historical legacy, a process that often leads to illogical, confusing, and even contradictory provisions. For example, in Arkansas, a state where knife fights with large and long blades such as Bowie and Arkansas toothpicks were once commonplace,[94][113] a state law made it illegal for anyone to “carry a knife as a weapon,”[114] which stipulated that any knife with a blade of 3.5 inches (8.9 cm) or more was prima facie evidence of this. that the knife was carried as a weapon. nevertheless allows a complete exemption from the law if “while travelling”. [115] The legislative amendments also provide for an updated definition of percussion knives in response to changes in weapon design.
