Many revellers in Plymouth will be asked to walk through a knife-detecting machine on Friday and Saturday night.
Police will be deploying two of the so-called "knife arches" at Mutley Plain and other areas of the city.
The portable knife arches are similar to metal detectors used in airports and can be assembled within minutes. Extra police patrols are also being brought into the city.
Senior officers said the city did not have a particular issue with knife crime, but deploying the arches, as well as extra patrols, would help to reassure the public.
Three men have been charged with attempted murder after the Mutley Plain stabbing last week.
The victim was getting into a taxi when he was seriously hurt in the assault.
The suspects have all been remanded in custody by Plymouth Magistrates' Court to appear before the city's crown court on 29 April.
The victim, who has not been named, suffered multiple stab wounds in the attack. He is being treated at Derriford Hospital where his condition has been described as stable.
Knife arches are a sensitive issue in Britain, where they've been criticised by civil liberties campaigners.
The police are keen to make sure their deployment on the streets of Plymouth is as uncontroversial as possible, in an attempt to maintain a consensus of support for their use.
"Officers will be on hand to explain why they're being deployed and no one will be forced to walk through an arch.
But anyone who refuses, will, of course, mark themselves as potentially worthy of further police interest."
Knife Arch Operation in Gloucester
|This man should be arrested for stupidity alone.|
Local police set up a knife arch at Goldhawk Road Tube station last Saturday (14 June) in a bid to tackle knife crime in the area.
The Shepherd’s Bush Green Safer Neighbourhood Team carried out spot checks on people coming out of the station, who were met by an airport-style gateway and officers carrying hand-held scanners.
“We won’t tolerate people carrying knives,” said Sergeant Ian Lewis.
“Evidence shows it is predominantly young men of all ethnic backgrounds who carry knives,” he said. “There is also evidence of females carrying them,” he added, pointing to a female officer on hand to assist with searches. There were plain clothes police officers outside the station area for backup.
During the two-hour operation, 24 people of all ages and backgrounds were stopped and searched, one knife was surrendered and one arrest made, on an unrelated matter.
“Knife crime is not particularly bad in this area,” Sergeant Lewis said. “There are other boroughs that are much worse.”
