Brothers were locked up for knife attacks in Matlock with a judge warning a man could have been murdered.
Derby Crown Court heard Harry Stones, 20, pulled a knife on a man when challenged to a fight in Hall Leys park on August 3.
Harry lunged at him then ran off with his brother Thomas, 18.
A week later Thomas pulled a knife on a man who pinned him against a shed, stabbing him twice in the chest and abdomen said Alex Wolfson, prosecuting. He needed eight stitches and was kept in hospital overnight.
Custody of 18 months was ordered for Harry who admitted affray and having a bladed article. Thomas pleaded guilty to wounding and affray. He got two years custody. The brothers lived on Jackson Tor Road, Matlock.
Judge Jonathan Gosling, said: “Anybody who takes up a knife and uses it in that way has to receive a custodial sentence.”
Sentencing on Monday, he told Thomas: “I know you were pinned against a wall at the time. I know trouble came to you in numbers but you knew what you were about. You were lucky you didn’t kill him. You could easily have done.” Referring to the Hall Leys incident, the judge added: “It would have been terrifying for people in the park during daylight who happened to be there.”
