A drunk mum who was found with a knife in the street also had a screwdriver hidden down her bra.
Kirsty Smith, also known as Slipper, was discovered with the blade when she was arrested following an incident in North Shields.
A court heard that police were called to Wallsend Road after a report of a disturbance one evening last month.
Smith was standing at the scene and immediately became aggressive when officers tried to speak to her, resulting in her being arrested for being drunk and disorderly.
However, when searched, the 35-year-old was found to be in possession of a small lock knife and a screwdriver, the latter being discovered down her bra.
Now, Smith, of Wallsend Road, North Shields, has avoided an immediate stint behind bars, despite having two previous weapon-related offences and a robbery offence on her record, after she pleaded guilty to possessing a bladed article and being drunk and disorderly.
Clare Irving, prosecuting at North Tyneside Magistrates' Court, said officers were called to Uppal's Food Store, on Wallsend Road, on May 7 this year after reports of a disturbance.
They tried to speak to Smith at the scene but she failed to comply and began shouting and swearing.
Ms Irving said: "She's arrested at just before 7.50pm and searched and a small lock knife is found in her pocket.
"There's also a 12-inch screwdriver inside her bra. That doesn't constitute a bladed article, so there's no charge for that.
"She's further cautioned and arrested. She's still obstructive and refusing to comply."
The court heard that Smith had to be restrained after trying to kick out and continued to refuse to give her identity at the police station.
Jonathan Cousins, defending, said Smith, who has two past convictions for possession of a bladed article from 2008 and 2011 and one for robbery in 2011, when she was jailed for three years, was ashamed of her behaviour.
Mr Cousins added: "What she had with her was attached to her key ring that also had a small blade that came out and locked in place.
"When it isn't pulled out, it's in the shape of a key. She was entirely unaware of the difficulties with the legislation and that it may constitute an offence.
"There's no suggestion is was brandished."
The court heard that Smith wasn't part of the initial disturbance, which prompted the police to be called.
Giving her a 12-month prison sentence, suspended for 12 months, chairing magistrate, Keith McIntosh, said: "We are in a knife culture at the moment with a lot of youths carrying knives around and we have a lot of people dying after being stabbed.
"There's no excuse for carrying a blade, even a small knife keyring. On top of which, you had a screwdriver, which beggars belief why you were carrying a screwdriver where you were - that doesn't make much sense."
