Adam Doran, 28, launched an unprovoked drink-fuelled attack on the boyfriend of a woman he was staying with.
A group had been having drinks at the house in Brickiln Street, Brownhills, on April 26.
Doran starting bickering with the man, aged 36, and after he went to the toilet, Doran reached for a knife from the kitchen drawer which he put inside his jacket.
His friend pleaded with him to put it away, which he eventually did. But he took it out again when the man left the room for a second time.
When he returned, Doran shoved him against the wall and pulled the knife out.
Despite attempts from others in the house to get Doran to stop and remove the knife from him, he stabbed the man four times causing serious internal injuries.
Although recovering, the 36-year-old’s injuries have changed his life forever. He’s on lifelong medication and is unable to work.
Doran ran off after the attack. Police were called, and officers found him intoxicated in nearby Wessex Court, he was lying face down in blood-stained clothing.
Doran, from Wilners View, Pelsall, pleaded guilty to wounding at Wolverhampton Crown Court on Monday. He was sentenced to 10 years in prison, with five years extended and an indefinite restraining order against the man he attacked.
Detective Sergeant Chris Jones, from our force CID, said: “This was a shocking attack following a minor disagreement.
"The amount of violence used was senseless and unnecessary.
“Knife crime has tragic consequences, my thoughts are with the man who suffered during this horrific attack and also those who witnessed it. The effects will no doubt be long lasting.
“I hope Doran's admission of guilt offers him some comfort and wish him all the best with his recovery."
