The 31-year-old man was assaulted with a kitchen knife and meat hammer at his home in Ruskin Road, Tottenham, sometime between 4pm and 5.30pm on Thursday, October 15.
It is believed he was arguing with two other men when a fight erupted and he was left with serious injuries to his head, neck and hands.
The victim chased the two men into the street and hurled a bottle at them as they jumped into a blue Ford Focus with a 51 number plate.
He was then found by a member of the public who immediately called the police. He was treated at the scene before being rushed as a priority to the hospital.
The first suspect is described as being of Mediterranean appearance, about 30-years-old and 5ft 10ins, of a muscular stocky build with short black hair going grey and full length tattoos on both arms – one of which is a flame pattern. He is thought to have been wearing a black jumper, blue jeans and white trainers.
A stab victim was spotted stumbling the streets in broad daylight covered in blood as he tried to chase his attackers.
The other suspect is described as being of Mediterranean appearance, about 30-years-old and 5ft tall, of slim build with a gap in his front teeth and a tattoo of Alicea or similar on his neck.
