TOOWOOMBA police are warning people about carrying credit card knives which are illegal.
Three people in as many weeks have appeared before the city's Magistrates Court charged with "unlawful possession of weapons category A, B or M" after being found with the offending items when passing through Brisbane West Wellcamp Airport.
The items look like any other plastic credit card but have a 5cm fold-away blade attached to the back.
In separate incidents, airport security had found a 19-year-old man carrying a credit card knife in his wallet as had a 48-year-old man while a 57-year-old woman was found with one in her purse.
The credit card knives, usually bought online, are considered under Queensland law to be a Category M weapon.
Darling Downs Detective Inspector Dave Isherwood said people had to be aware that credit card knives were a prohibited item under the Weapons Act.
"People need to be aware that they (credit card knives) are not considered a normal knife," he said.
"It's a concealed weapon and so a prohibited item under the Weapons Act.
"It's a restricted item."
Each of three people appearing before the court pleaded guilty to the charge of possessing a category M weapon, each claiming they had no idea the credit card knife was illegal.
The woman said she had been given the card by her son to use if needing to cut up items such as fruit when travelling and the 48-year-old man said a friend had given him the item which he had used for such activities as cutting string from parcels.
He had not been travelling by plane but had been at the airport having coffee with his daughters who were travelling on holiday, the court heard.
The 19-year-old man was fined $300 while the 48-year-old man and 57-year-old woman were each released on a six-month good behaviour bond.
No convictions were recorded against any of the three.
