Mark Fellows, 42, dubbed The Iceman, was stabbed in the head and the neck at the maximum security HMP Wakefield on Saturday.
The double murderer was treated by prison medics. He was left with a scar after a similar attack in 2019.
Fellows was the 'gun for hire' called on to slaughter a leading figure in a rival gang, Paul Massey, 55, in 2015 with an Uzi submachine gun.
Dressed in army fatigues, he peppered Massey with shots and then pursued his target up the driveway of his home on Manchester Road in Clifton, Salford, to finish him off.
Known as Salford's 'Mr Big, Massey was one the city's most notorious and feared figures but he died on his own doorstep.
Three years later Fellows murdered Massey's pal from Liverpool, John 'Scouse' Kinsella, 53.
