Crime prevention tips to promote the safe sale and storage of knives.

Display relevant signs

If you sell knives, you must clearly display a sign which reads, “It is an offence to sell a knife to a person under the age of 18. Proof of age may be required.”

Store and display knives safely

To make sure of the safe storage and display of knives:

• display empty packets on shelves
• store knives in cabinets or in a storeroom
• ensure display cabinets or other storage areas are locked and only accessible by staff members
• ensure CCTV cameras cover knife storage areas.

Know the difference between prohibited and controlled weapons

Businesses responsive for knife sales should understand what a prohibited weapon is and what a controlled weapon is.

Prohibited weapons

Prohibited weapons include:

• swords
• flick knives
• butterfly knives
• double ended knives
• push knives
• daggers.

See the full list of weapon definitions.

Controlled weapons

All other knives are a controlled weapon.

Know the law around selling weapons

You must understand the law regarding weapon sales.

• You cannot purchase, use, or possess a prohibited weapon without a Chief Commissioner’s Approval or a Governor in Council Exemption. This includes possession to sell.
• You cannot sell a prohibited or controlled weapon to anyone under 18 years of age.
• You cannot advertise or sell a prohibited weapon, to anyone, without a Chief Commissioner’s Approval or a Governor in Council Exemption.

Record sales of prohibited weapons

You must record the sale of prohibited weapons.

The record must include:

• a description of the weapon, including identifying marks or serial number
• the buyer’s name, address, telephone and date of birth
• evidence of the buyer’s Exemption or Approval
• the sale date and time
• the seller’s name and address.

You must keep this record for 3 years.

Victoria Police can inspect these records at any time.

If a knife has been stolen

If there has been a theft of a knife at your business:

• tell your supervisor or manager immediately
• As a witness, report the offence rather than waiting for your manager to report it
• no issue is too small to report, report any suspicious behaviour to police
• do not confront the thief if they are still in your store - get out or find a safe place
• do not touch anything
• If there is security footage, download it for police.
