A 23-year-old woman hit another female over the head with a stiletto in a row at a nightclub.
The victim was left with cuts to her head after she was attacked by Olivia Mahon at Rosies in Birmingham.
The assault happened just four months after Mahon punched a man and a woman in a car park on a night out, a court heard.
It was accepted that, during the Rosies incident, she had acted in "excessive self defence" when the complainant ran towards her.
The court also heard she confessed she had "links with criminals" but had tried to break away from them, Birmingham Live reports.
Mahon from Birmingham, admitted a charge of inflicting grievous bodily harm.
At Birmingham Crown Court she was sentenced to six months, suspended for 18 months on October 28.
She was also ordered to pay the victim £200 compensation, carry out 150 hours of unpaid work as well as complete 25 days of rehabilitation activity including anger management support.
The victim had been at Rosies celebrating a friend's birthday in the early hours of October 13, 2019 when she noticed her boyfriend in the queue being "pushed and shoved by a number of males", said prosecutor Gary Rutter.
He added: "It escalated into an altercation. She became involved pushing one man away.
"At some point she became involved with the defendant and she says she was struck over the head by the defendant using her stiletto. She was aware of the movement of the defendant and blow over her head.
"She remembers falling heavily and the feeling of blood. She crouched down to avoid further blows."
The prosecutor stated one witness saw the victim being "whacked" on the head by Mahon holding the shoe.
She was taken to hospital where cuts to her head were dressed and glued while Mahon was detained by security staff and arrested.
Michael Tanney, defending, told the court Mahon was wearing sliders having taken her stilettos off and placed them on the table.
He argued his client did not react out of "'outrage or vengeance" but instead did a "reflexive thing" by reaching for the stiletto when the victim came running towards her.
Mr Tanney added: "What I have observed is a degree of empathy exhibited by Ms Mahon.
In her words she said: 'There was no need for it. It was morally wrong. I have seen the injuries and I'm upset. She does deserve justice. She has clearly been in a lot of pain and affected mentally and physically'.
"Here is a young girl, aged 23, with a degree of insight and self awareness and is able to empathise with the complainant. It all bodes well for anger management within the auspices of a suspended sentence.
"She also says, which she didn't have to say but disarmingly does: 'I concede I have links with criminals but I have done my best to break from them and not associate with them."
