A switchblade is a pocketknife with a sliding or pivoting blade contained in the handle which is extended automatically by a spring when a button, lever, or switch on the handle or bolster is activated. Virtually all switchblades incorporate a locking blade, where the blade is locked against accidental closure when the blade is in the open position. It is unlocked by a mechanism that allows the blade to be folded and locked in the closed position.
A balisong, also known as a butterfly knife, fan knife or Batangas knife, is a type of folding pocketknife that originated in the Philippines. Its distinct features are two handles counter-rotating around the tang such that, when closed, the blade is concealed within grooves in the handles. A latch sometimes holds the handles together; typically mounted on the one facing the cutting edge.
A ballistic knife is a knife with a detachable blade that can be ejected to a distance of several meters/yards by pressing a trigger or operating a lever or switch on the handle. Spring-powered ballistic knives first appeared in books and press reports on Soviet and Eastern Bloc armed forces in the late 1970s. Commercially-produced ballistic knives briefly gained notoriety in the United States in the mid-1980s after they were marketed and sold in the United States and other Western countries. Since then, the marketing and sale of ballistic knives to civilians has been restricted or prohibited by law in several nations.
Assault occasioning grievous bodily harm is a term used in English criminal law to describe the severest forms of battery. It refers to two offences that are created by sections 18 and 20 of the Offences against the Person Act 1861. The distinction between these two sections is the requirement of specific intent for section 18; the offence under section 18 is variously referred to as "wounding with intent" or "causing grievous bodily harm with intent", whereas the offence under section 20 is variously referred to as "unlawful wounding", "malicious wounding" or "inflicting grievous bodily harm".
In criminal law, incitement is the encouragement of another person to commit a crime. Depending on the jurisdiction, some or all types of incitement may be illegal. Where illegal, it is known as an inchoate offense, where harm is intended but may or may not have actually occurred.
Offer and acceptance are generally recognized as essential requirements for the formation of a contract. Analysis of their operation is a traditional approach in contract law. This classical approach to contract formation has been modified by developments in the law of estoppel, misleading conduct, misrepresentation, unjust enrichment, and power of acceptance.
In criminal law, a mistake of fact may sometimes mean that, while a person has committed the physical element of an offence, because they were labouring under a mistake of fact, they never formed the mental element. This is unlike a mistake of law, which is not usually a defense; law enforcement may or may not take for granted that individuals know what the law is.
An assisted-opening knife is a type of folding knife which uses an internal mechanism to finish the opening of the blade once the user has partially opened it using a flipper or thumbstud attached to the blade.
Partridge v Crittenden [1968] 1 WLR 1204 is an English legal case which was heard by the Divisional Court of the Queen's Bench Division of the High Court of England and Wales on appeal from Chester magistrates' court, and is well known for establishing the legal precedent in English contract law that advertisements are usually considered to be invitations to treat.
Spencer v Harding (1870) LR 5 CP 561 is an English contract law case concerning the requirements of offer and acceptance in the formation of a contract. The case established that an offer inviting tenders to be submitted for the purchase of stock did not amount to an offer capable of acceptance to sell that stock, but rather amounted to an invitation to treat.
Knife legislation is defined as the body of statutory law or case law promulgated or enacted by a government or other governing jurisdiction that prohibits, criminalizes, or restricts the otherwise legal manufacture, importation, sale, transfer, possession, transport, or use of knives.
An offensive weapon is a tool made, adapted or intended for the purpose of inflicting physical injury upon another person.
English criminal law concerns offences, their prevention and the consequences, in England and Wales. Criminal conduct is considered to be a wrong against the whole of a community, rather than just the private individuals affected. The state, in addition to certain international organisations, has responsibility for crime prevention, for bringing the culprits to justice, and for dealing with convicted offenders. The police, the criminal courts and prisons are all publicly funded services, though the main focus of criminal law concerns the role of the courts, how they apply criminal statutes and common law, and why some forms of behaviour are considered criminal. The fundamentals of a crime are a guilty act and a guilty mental state. The traditional view is that moral culpability requires that a defendant should have recognised or intended that they were acting wrongly, although in modern regulation a large number of offences relating to road traffic, environmental damage, financial services and corporations, create strict liability that can be proven simply by the guilty act.
In English contract law, an agreement establishes the first stage in the existence of a contract. The three main elements of contractual formation are whether there is (1) offer and acceptance (agreement) (2) consideration (3) an intention to be legally bound.
An invitation to treat is a concept within contract law which comes from the Latin phrase invitatio ad offerendum, meaning "inviting an offer". According to Professor Andrew Burrows, an invitation to treat is
an expression of willingness to negotiate. A person making an invitation to treat does not intend to be bound as soon as it is accepted by the person to whom the statement is addressed.
Payne v Cave (1789) 3 TR 148 is an old English contract law case, which stands for the proposition that an auctioneer's request for bids is not an offer but an invitation to treat. The bidders make the offers which can be accepted by the auctioneer.
City and Westminster Properties (1934) Ltd v Mudd [1959] Ch 129 is an English contract law case, regarding the parol evidence rule. It illustrates one of the large exceptions, that a written document is not deemed to be exhaustive of the parties intentions when there is clear evidence of a collateral contract. It shows that even evidence from outside a written agreement may contradict evidence inside it.
Burglary is a statutory offence in England and Wales.
The purposive approach is an approach to statutory and constitutional interpretation under which common law courts interpret an enactment within the context of the law's purpose.
