The 22-year-old musician was attacked by two men in hooded tops in the early hours of Saturday in Highgate, north London.
Ironik received a knife wound to the buttock during the attack and was taken to a nearby hospital for treatment.
Recuperating yesterday, he thanked fans for their support via his Twitter feed, adding: "It could have been much worse."
The rapper, real name James Charters, was returning from a gig in Essex at the time of the incident.
Arriving home at around 3.30am, he was approached by the pair, wearing dark clothes including hooded tops. After stabbing Ironik, the assailants fled with jewellery belonging to the rapper.
The personal items were later recovered by police. No arrests have been made in the case, a Scotland Yard spokesman said.
Best known for his No 3 hit Tiny Dancer featuring Sir Elton John, Ironik is a Prince's Trust ambassador and a vocal anti-knife campaigner.
Following his treatment, he reassured fans in a series of tweets.
He said: "It's been a crazy last couple of days and this whole experience is quite surreal. But they say what doesn't kill you only makes you stronger."
This was followed by the message: "I wanna thank each and every one of my friends, family and supportive fans that have showed me lots of much love."
And: "It could have been much worse so thank God it weren't and I'm just resting and recovering."
