A walking stick, tool, bottle or household item is not an offensive weapon absent an intention to use it as such. A recent Court of Appeal decision shows that intention is only part of the question: the prosecution must also prove that the defendant was having the object as a weapon, rather than merely using it in the same instant that an assault began.
The distinction mattered in Kalinga v R [2026] EWCA Crim 1135, where a crutch was used during a street confrontation. The Court of Appeal upheld the assault conviction but quashed the separate conviction for possessing an offensive weapon.
What is an offensive weapon?
Section 1 of the Prevention of Crime Act 1953 makes it an offence, without lawful authority or reasonable excuse, to have an offensive weapon with you in a public place. The legislation recognises three broad types of offensive weapon.
Some articles are made for causing injury, such as a weapon designed for attack, such as knuckle-dusters or nunchakus. Others become offensive weapons because they have been adapted for that purpose, for example a baseball bat with nails or spikes driven into it. The third category deals with ordinary objects that are not offensive but have been used in an offensive manner, here we might think of somebody who is brandishing a screwdriver towards another person.
Using an object does not equal having the object as a weapon
It is natural to assume that if an object is used as a weapon, then it must be an offensive weapon. The law is not that clear cut. The 1953 Act is principally preventive: it criminalises being equipped with a weapon in a public place, not every assault in which an object happens to be used. There’s good reason for that; we already have laws to deal with assaults!
There must therefore be a sufficient distinction between forming the intention to use the article as a weapon and the assault itself. If picking up the item, forming the intention and striking are all part and parcel of one immediate act, the separate possession offence is unlikely to be made out. The assault can still be prosecuted, and use of an object will make it more serious, but that does not prove the offensive weapon charge.
What happened in Kalinga?
Mr Kalinga became involved in an altercation in Bournemouth. The other man had two crutches. A passer-by took one crutch and handed it to Mr Kalinga, who used it to strike the man within literally one or two seconds. He was convicted of assault occasioning actual bodily harm and of having an offensive weapon in a public place.
The Court of Appeal held that the trial judge should have withdrawn the offensive-weapon count from the jury. There was no evidence of a meaningful interval in which Mr Kalinga possessed the crutch with the relevant intention before the assault. Receiving it and using it were part of the same incident. The weapon conviction was quashed, while the assault conviction and its sentence remained unaffected.
Where is the dividing line?
There is no fixed number of seconds that turns an object into an offensive weapon. The court looks at the whole sequence. A person who takes a baseball bat from home, carries it towards a confrontation and intends to use it if challenged is in a very different position from someone who grabs a nearby object instinctively during an attack.
Earlier cases illustrate the point. Taking a hammer from its case and immediately using it, or producing an ordinary penknife already carried for an innocent reason in the heat of an incident, may fail to establish the separate offence. By contrast, carrying or fetching an article in anticipation of violence can provide the necessary separation between possession and use. Evidence of threats, travel, concealment or prior preparation may be decisive.
Why the distinction matters
A single incident can generate both an assault charge and an offensive-weapon charge, but each must be proved on its own elements. The jury should be given a clear route to verdict: what was the article, when did the defendant intend it to be used to cause injury, and was the defendant having it as a weapon before or apart from the assault? If the evidence shows only instantaneous use, Kalinga may require the possession count to be withdrawn.
The distinction also affects plea advice, sentence and the orders a court may make. CCTV, body-worn video, witness accounts, messages and precise timings can all change the answer. A brief but accurate chronology is often more useful than a general description that the defendant 'had a weapon'.
