A woman waved a machete around in the middle of the road after she 'lost it' in a row at home.
Claire Taylor, 46, an unemployed former shop manager, repeatedly stabbed the road and lamp-post during her outburst although no-one was harmed.
Taylor had been living at an address on Moss Vale Road in Stretford with her partner of five years and a lodger when there was an argument at the property on March 22, Manchester Crown Court heard.
The defendant emerged from the house into the garden with a machete in her hand, prosecutor James Preece told the court on Friday.
A passing taxi driver saw the defendant with two others in the road 'swinging the machete around'.
The cabbie saw her stabbing the floor repeatedly with the blade and appeared to be 'in her own world', the court heard.
Taylor's partner urged her to go inside and she did but not before striking a lamp post with the machete on the way in, said the prosecutor.
Police were called after receiving numerous complaints from neighbours of a woman with a machete in the road.
Taylor emerged from the house, leaving the machete inside, and was arrested.
Police body-cam footage showed Taylor was compliant as she was escorted into the rear of a prison van and appeared to become emotional.
Police found the machete with a 30cm blade inside the house although Taylor's partner claimed it was a 'garden tool', the court heard.
Taylor admitted she had rowed with the lodger who she said she did not get on with.
She conceded she 'lost it' and said she wanted to slash his tyres with the blade. She insisted she would 'never hurt anyone'.
David Morton, defending, said his client had endured 'an absolutely awful time' and had been to 'some very dark places indeed'.

She had been 'stoic' about her past troubles but was now full of optimism for the future, said Mr Morton.
She was 'full of remorse' for what she had done.
Judge Patrick Field QC told her: "You must recognise that what you did on March 22 by taking up that evil looking knife and waving it around in the highway, even if it wasn't your intention to hurt anybody else, was disgraceful and unacceptable behaviour."
He added: "It's up to judges to take knife crime seriously and I do but I also have to take account of the fact that this was uncharacteristic behaviour."
The court heard had no previous convictions and only had a caution from 2007 to her name.
The judge went on: "I accept that this was an occasion when you lost it and lost self-control and mercifully you lost self-control without disastrous consequences because there could have been waving a knife around like that."
Taylor, who admitted a single charge of possessing a knife in a public place, was handed a 15-month community order including 20 days of rehabilitation activity.
"You must understand that I have dealt with you leniently," said the judge as he told her she was free to leave the dock.
