Enock Kitopi, 23, and Tyrell Chester, 22, got off a moped to attack the victims - one 19 and one 18 - in an alleyway near Silver Road.
Kitopi, 23, “chopped” a large bowie knife into the forehead of one, before stabbing him in the chest, Norwich Crown Court was told.
The younger victim was stabbed in his arm so severely that the bone was left protruding as he attempted to protect himself from being knifed in the throat by Chester during the attack in September 2022.
