A teenager who used a Rambo-style survival knife to murder a 24-year-old man during a street fight in Wolverhampton has been jailed for life.
Shamari Hanchard-Kerr, who was on bail for assaulting two police officers when he killed Razi Ul-Hassan, was ordered to serve at least 15 years before being considered for parole.
Sentencing the 18-year-old at Birmingham Crown Court, Mr Justice Simon described him as a bully who had acted aggressively before the fatal confrontation in Wolverhampton last August.
Although the judge accepted that Hanchard-Kerr had been pursued by three men, he told him: "You then turned and began a violent and unjustified attack.
"What is clear is that you used grossly disproportionate force."
Hanchard-Kerr, of Cheltenham Avenue, Wolverhampton, was convicted of murder last month after a jury heard how he stabbed three men during a row over a debt.
Each of the victims was stabbed three times, but although two of them survived, Mr Ul-Hassan suffered a fatal chest wound.
Hanchard-Kerr's identical twin brother, Kamahl Hanchard-Kerr, also stood trial accused of murder, but pleaded guilty to affray after the jury failed to reach a verdict on the more serious charge.
Kamahl Hanchard-Kerr, also of Cheltenham Avenue, was sentenced to 18 months' detention for his involvement in the violence.
The brothers, then aged 17, were picked out at identity parades by witnesses to the killing, which happened in Crosby Close, Whitmore Reans, on August 12 last year.
Detective Inspector Martin Hurcomb, who led the murder investigation, said: "We are pleased with today's sentences, as are Razi's family, although no sentence can ever replace his life. Our thoughts and sympathies are with Razi's family at this time.
"It is clear that he was much-loved by his family and is greatly missed."
