Colin Bown was stabbed in the chest after four men confronted him on a play area off the Model Village in Shirebrook in the early hours of Monday.
Colin, 37, was rushed to hospital after the wound punctured his lung just inches from his heart.
Police are hunting the men who are described as being eastern European, possibly Polish.
Colin told Chad He had fought with two men and two more who jumped over a fence to surround him.
“The guy behind me pulled a knife and hit me. I felt a sharp pain in my chest, said Colin
“It wasn’t till I looked down I saw there was blood all over.
“I pulled the knife out and they ran off.”
His wife Tammy Bown said: “He came in and said he had been stabbed and told me to phone an ambulance.
“I thought he was messing about.
“When I looked at the wound I didn’t think it looked so bad, but he said he felt faint.
“I put pressure on his chest with a tea towel and in a few minutes there was blood all over the wall and floor.
”I was just shocked I couldn’t believe it.
He was taken by ambulance to the Queens Medical Centre where a pipe was inserted into his lung to drain the blood.
Derbyshire Police said Police have issued descriptions of men they want to trace.
A spokesman said the offender was wearing a grey Everlast top, dark Nike tracksuit bottoms, bright yellow or green trainers and a black and green baseball cap with a circle logo with wings sprouting from it.
One of the other men was tall, of stocky build and with a bald head.
They were believed to be Eastern European, possibly Polish.
Anyone who recognises those descriptions should call Derbyshire police on 101 or Crimestoppers on 0800 555 111.
