A Melbourne man stabbed during a road rage incident in the city's southwest says he remembers the perpetrator smiling through the attack.
Andrew, who did not give his surname, had gone to the grocery store on the afternoon of November 2 last year when a grey Volkswagen hatchback broke in front of him, swerved, and cut him off, he said.
Feeling tormented and annoyed, he pulled over and got out of his Ford Ranger ute along Carinza Ave at Altona Meadows.
A verbal altercation followed, before a passenger of the Volkswagen sprinted towards him, brandishing a knife.
"I went to turn around to get back into the car but I didn't make it," Andrew told reporters on Wednesday.
"As he was stabbing, he was looking at me over my left shoulder, smiling.
"He was enjoying it."
The 54-year-old was hospitalised with serious injuries - two stab wounds in the lower back.
Police are seeking the public's help to find the offender along with the driver of the Volkswagen, which they say wasn't stolen. Officers have spoken to the car's owner but are yet to identify the pair.
The attacker is described as aged in his late teens to early 20s, of African appearance, about 170cm tall with a slim build, and black curly hair in an afro style. He was wearing black-and-white runners.
The driver is of African appearance and also looks to be in his early 20s, police said.
"Andrew doesn't know who these people are, they don't know who he is," Detective Senior Constable Kai Wilkie-Bourke said.
"It's just violence for the sake of violence."
The two men in the hatchback fled the scene and were last seen travelling north towards Werribee, police said.
Andrew has struggled physically, mentally, and financially since the incident, he said. He has a stiff back and nerve pain.
"I said goodbye to my mum and dad, my kids, my family. I thought that was it," he said.
"Knives destroy lives and it's destroyed mine."
Police have released CCTV images of the two men, and urged anyone with information to contact Crime Stoppers.
