Is carrying a knife in public legal in India? Small utility knives are generally tolerated, but the Arms Act, 1959 treats blades longer than 9 inches or wider than 2 inches as prohibited arms in public places, states and cities can set lower limits, and “self-defence” isn’t accepted as a lawful reason, so a knife that’s technically legal can still land you in trouble if police believe it threatens public order. This is general information, not legal advice, and the numbers below vary by state.
What You Need to Remember
- Baseline limit: blade longer than 9 inches or wider than 2 inches counts as prohibited in public
- State variation: some states use smaller limits, such as 6 inches in Madhya Pradesh
- Self-defence: carrying a knife for protection isn’t a lawful excuse under the Arms Act
- Religious exemption: Khalsa Sikhs may carry the kirpan, with some restrictions
- Penalty: imprisonment and/or fine under Section 25, with the length differing by source
The Law Behind It
The Arms Act does the heavy lifting.
- The Arms Act, 1959 and its Rules regulate manufacture, possession, sale and carrying of arms, including bladed ones, according to Legal Shouts
- Section 4 and Section 5 deal with prohibition and licensing, and knives become “prohibited” or licence-requiring only if they exceed certain specifications, according to one student blog
- There is no single central law that outright bans carrying knives, according to Law Legal Info, but the Act applies when a blade crosses the size thresholds
- Sources refer to both the Arms Rules, 1962 and the Arms Rules, 2016, so check which currently applies
The 9-Inch, 2-Inch Rule
This is the figure everyone quotes.
- Any knife with a blade length exceeding 9 inches or a blade width exceeding 2 inches is illegal to carry, according to Wikipedia’s Arms Act entry
- Such blades are classified as prohibited arms in public places unless held for domestic, agricultural, scientific or industrial purposes, according to Legal Shouts
- Carrying them without a licence is an offence under the Arms Act
- A licence for a knife is very rarely granted, according to the student blog
States Set Their Own Numbers
Notifications under Section 4 differ.
- Different states have issued notifications prescribing different sizes for the “prohibited” class, according to a post on the Indians For Guns forum
- That post says Madhya Pradesh treats a knife as prohibited if the blade is longer than 6 inches or broader than 2 inches, while Himachal Pradesh uses 9 inches and 2 inches
- It adds that the knife must have a sharp edge and be carried in a public place to be prohibited
- The same post claims Mumbai restricts pocket folding knives with blades over 3 inches, but it’s an old forum comment I couldn’t verify
- Law Legal Hub says in Maharashtra a knife over 9 inches needs a valid licence
The Public Place Test
Where you carry matters.
- Carrying any edged weapon in public places, including educational institutes, airports, railway stations and metro stations, is illegal, according to Legal Shouts’ sword explainer
- The same restrictions often apply at schools, courts and government buildings through security rules
- A knife in a locked toolbox in a vehicle is easier to defend than one in your waistband
Utility Knives and Pocket Tools
Ordinary tools are usually fine.
- Ordinary household or utility knives, such as kitchen knives, small pocket knives or tools, are generally legal, according to Law Legal Info
- A standard Swiss Army knife or Leatherman multi-tool with a blade under 9 inches, and most models have blades under 3 inches, is generally legal for domestic and utility purposes, according to Legal Shouts
- Context matters: a camping knife on a trek is different from the same knife in a crowded market at night
The Self-Defence Trap
Many people assume a knife is a safety tool.
- Carrying a knife specifically for self-defence in public doesn’t constitute a lawful excuse under the Arms Act, according to Legal Shouts
- The Bharatiya Nyaya Sanhita recognises the right of private defence, but using a knife in a fight, even if you later argue self-defence, will invite police investigation, arrest and a complex legal process, according to the same source
- So the right of private defence doesn’t turn carrying a weapon into a lawful practice
Intent and Local Orders
A legal knife can become a problem.
- Even a legal knife can become illegal if police believe it may be used to cause harm or disturb public order, according to Law Legal Info
- Carrying a knife without a reasonable purpose may still lead to police action under local laws, such as orders under Section 163 of the BNSS, formerly Section 144 of the CrPC, or local police acts, according to the student blog
- District authorities sometimes ban sharp weapons in public during festivals, protests or tension
Religious and Cultural Exemptions
A few exceptions exist.
- Khalsa Sikhs may carry the kirpan in public, under Article 25 of the Constitution, according to Wikipedia and Law Legal Hub
- There may be restrictions on the size of the kirpan, and some states have specific rules, according to Wikipedia
- Nihang Sikhs can carry edged weapons and firearms after obtaining a licence under the Arms Act, according to the same source
- The Gurkha khukri within the community and swords during cultural processions with police permission are other exceptions, according to Legal Shouts, and Shia Muslims may carry swords and knives during Muharram processions with police permission
Penalties
The numbers differ.
- Possession of a prohibited arm without a licence, including oversized blades, switchblades and daggers, carries up to three years’ imprisonment and/or a fine under Section 25, and up to seven years for repeat or aggravated cases, according to Legal Shouts
- I couldn’t confirm those figures against the Act’s text, so check the section for the exact range
- Police can also seize the knife and register a case, and bail depends on the court
What Counts as a Prohibited Type
Some blades are risky whatever the size.
- Sword sticks, daggers, bayonets, throwing knives and switchblades are listed among problem items, according to Legal Shouts
- Possessing a sharp, functional sword without a licence, particularly in public, can lead to trouble under the Arms Act, according to the same source
- Blunt or decorative swords kept at home for display are unlikely to attract police attention, but the Act may technically still apply
Practical Guidance
A few habits reduce risk.
- Keep any knife you carry small, plain and tied to a clear purpose, such as work or a trek
- Carry it in a bag or toolkit, not on your belt
- Don’t carry it into schools, airports, stations, courts or crowded events
- Check your state’s notification and your city’s police orders
- If stopped, stay calm, explain the purpose and ask for the order cited
For Hikers, Trekkers and Tradespeople
Work and outdoor use are better protected.
- Domestic, agricultural, scientific and industrial purposes are the recognised exceptions, according to Legal Shouts
- Keep tools in their cases while travelling, and carry any receipts or work documents
- Larger knives are safer on private or forest land than on city streets, though forest rules may also apply
Where the Sources Disagree
A few details need care.
- The penalty ranges, three or seven years
- Whether Arms Rules 1962 or 2016 apply
- City-specific limits like Mumbai’s, which come from unverified comments
- Most of these are law-blog explainers, so read your state’s Section 4 notification
