Is It Legal to Carry Swiss Army Knives in Singapore?

Last updated on September 4, 2026

In Singapore, strict laws regulate the possession and carrying of weapons in public. While many people carry small knives or multi-tools for practical reasons, doing so without a lawful purpose can potentially expose them to criminal liability. This is especially relevant for commonly used items such as Swiss Army knives, folding knives, or multi-tools.

So, is it legal to carry Swiss Army knives in Singapore? The short answer is: it depends on whether a Swiss Army knife is considered a weapon, as well as why and where it is carried.

This article covers:

What is Considered a “Weapon”?

Under the Guns, Explosives and Weapons Control Act (GEWCA), the term “weapon” covers a broad range of objects that are capable of being used to cause injury, including certain types of knives.

These weapons are categorised into three different types based on the level of risk they pose to safety and security. The table below sets out these categories and the corresponding licensing requirements:

Category	Description	Examples of weapons	License type required
Type 1	Weapons designed primarily to cause hurt and with little or no legitimate day-to-day use	Crossbows, throwing knives, knuckledusters, throwing stars, butterfly knives, nunchucks, bayonets, swords, spears	Individual license required
Type 2	Weapons designed to cause hurt but which also have legitimate uses	Sporting bows and arrows, or bayonets, swords and spears that have been blunted so that they are not capable of causing serious injury or death	Class license required
Type 3	Items that are principally designed as tools or implements for legitimate activities but which may nevertheless be misused to cause hurt	Axes, machetes, parangs, diving knives, hunting knives and scythes	No license required (exempted)

Are Swiss Army knives considered a “weapon” under the GEWCA?

No, Swiss Army knives are not specifically listed within any of the regulated weapon categories under the GEWCA. A Swiss Army knife is generally a folding multi-tool incorporating one or more small blades together with practical implements such as scissors, screwdrivers, bottle openers and tweezers. Unlike knives designed primarily for combat or self-defence, Swiss Army knives are intended principally for utility and everyday practical use.

Singapore Police Force guidance expressly lists “Manual Foldable Knife / Swiss Army Knife” as a non-regulated item. This means that there is generally no requirement to obtain approval or a licence to purchase, import, possess or own a Swiss Army knife in Singapore.

However, they may still be treated as offensive weapons under other laws depending on the circumstances in which they are carried, used, or intended to be used (see below).

Is it Legal to Carry a Swiss Army Knife in Singapore?

Although Swiss Army knives are generally lawful items that do not require licensing or approval under the GEWCA, carrying one in public may attract criminal liability under the Corrosive and Explosive Substances and Offensive Weapons Act (CESOWA).

This is because the relevant legal issue is not whether the knife is a regulated weapon under the GEWCA, but whether it constitutes an “offensive weapon” under the CESOWA.

Under section 6(1) of the CESOWA, any person who carries an offensive weapon in a public place without lawful authority or lawful purpose commits an offence.

An “offensive weapon” refers to any instrument which, if used as a weapon of offence, is likely to cause hurt. This means that even an otherwise ordinary object can potentially become an offensive weapon, depending on the surrounding circumstances and the carrier’s intended use. For example, a Swiss Army knife carried as part of camping equipment during a hiking trip is likely to be viewed very differently from the same knife being carried during a confrontation, is concealed, or possessed for the purpose of self-defence or intimidation.

As a result, a Swiss Army knife that is carried for genuine utility purposes or as part of a legitimate recreational activity, such as camping, may be lawful, whereas the same knife carried for intimidation, self-defence, confrontation or violence may potentially constitute an offensive weapon.

Situations where carrying a Swiss Army knife may amount to an offence

In 2023, a man who threatened doctors and nurses at Sengkang General Hospital with a Swiss Army knife and hurled vulgarities at them, while in a state of drug-induced paranoia, was sentenced to six weeks in jail. He had pleaded guilty to two offences under the Protection from Harassment Act, and four other charges, including one of carrying an offensive weapon (i.e. the Swiss Army knife), were taken into consideration for sentencing.

In another incident in 2023, a 61-year-old man in Toa Payoh allegedly charged at police officers while armed with a 39-cm long knife. Police seized not only the knife, but also a Swiss Army knife and a hammer from him. He was subsequently charged with possession of an offensive weapon in public.

These incidents illustrate that even where an item is not itself prohibited, criminal liability may arise from the circumstances in which it is possessed or used (e.g., in public places, and where the knife is used to threaten or harm another person).

Can You Carry a Swiss Army Knife for Self-Defence in Singapore?

Many people mistakenly assume that carrying a small knife “just in case” for personal protection is lawful.

As highlighted above, Singapore adopts a strict approach towards weapons and offensive weapons in public places. A person who carries a knife primarily for self-defence may have difficulty establishing that it was carried for a lawful purpose, if the circumstances indicate that it was actually intended for use against another person.

Carrying a Swiss Army knife, folding knife or similar bladed tool for self-defence may therefore expose you to potential criminal liability, even if the knife is never actually used and you are found to be in possession of it.

What are the Penalties for Carrying a Knife Without a Lawful Reason?

Under section 6 of the Corrosive and Explosive Substances and Offensive Weapons Act, it is an offence for a person to carry or have in their possession an offensive weapon without lawful authority or for a lawful purpose. Offenders can face a prison term of up to 3 years and caning.

The penalties become even more severe where scheduled weapons are involved, with offenders facing up to 5 years’ imprisonment and a minimum of 6 strokes of the cane. Scheduled weapons refer to offensive weapons that are listed in the First Schedule of the GEWCA, such as flick knives and swords.

For example, in 2022, a man who used a samurai sword – a scheduled weapon – to slash a pedestrian and several vehicles near Buangkok Square Mall was sentenced to 18 months’ imprisonment and six strokes of the cane after pleading guilty to multiple offences, including possession of an offensive weapon.

In Singapore, carrying a Swiss Army knife is not automatically illegal. Swiss Army knives and manual folding knives are generally lawful items that do not require licensing or approval under Singapore’s weapons-control regime. However, that does not mean they may be carried freely in all circumstances.

Whether carrying a Swiss Army knife is lawful depends heavily on the surrounding circumstances, including where it is carried, why it is carried and whether there is a legitimate reason for possessing it.

Given Singapore’s strong emphasis on public safety, it is always advisable to exercise caution and avoid carrying knives or bladed items unless there is a clear and legitimate need to do so. If you or a loved one has been charged with a weapons-related offence, you are strongly advised to consult a criminal defence lawyer who can assess the circumstances of your case and advise you on your next steps.
