A 23-year-old man injured during the same incident survived the attack.
Detective Chief Inspector Steve Handley said: "A warrant was executed at a property in Charlotte Road, Sheffield, as part of the ongoing murder investigation into the death of Jarvin Blake."
Earlier today, he described the murder as a 'mindless act of violence'.
The stabbing is being treated as a targeted attack.
Four men, two aged 26, one aged 25 and one 24, were arrested on suspicion of murder last week and later released under investigation as police enquiries continue.
DCI Handley added: "A 22-year-old father-of-three has lost his life due to a mindless act of violence in the middle of the afternoon on Thursday, March 8.
"Mr Blake and his friend, 23, were in the Burngreave area when a car pulled up on Catherine Street, at the junction with Brackley Street, just after 3pm and a group of people got out.
"Any information, no matter how insignificant you feel it may be, could greatly assist with the investigation and I would please ask you to get in touch."
