Police spotted Smith, 28 of Sampson Street, kneeling down beside a car just after 11pm on June 13, accessing the underside.

Asking her what she was doing, she said she was trying to get her possessions out of it.

Searching Smith, they recovered a nine-centimetre knife.

In Orange Local Court, solicitor Andrew Abraham said his client kept the knife for self-protection.

"I've spoken to my client several times and she's expressed remorse and said multiple times how foolish it was to have it in public," he said.

Magistrate David Day said often the people who carried knives for protection were the ones being stabbed.

"She's her own worst enemy," he said.

Smith, who appeared via video link after breaching parole, told Mr Day she planned to attend counselling, but Mr Day said he had lost count of the times he had heard it before.

"It's boring," he said.

Mr Day handed down the order, saying it would ensure she was supervised once she was released.
