The latest police phase to drive down knife crime began on Monday, (June 19) after it was revealed that thousands of people were charged with possessing a knife in the last 12 months.
According to the Metropolitan Police , since May last year, 2,706 people were charged with possession of a knife - 85% of all arrests for the offence.
A further 474 people received cautions related to knife possession.
London's knife crime
Operation Sceptre was launched last month, but after a "recent spike in knife crime offences", it was announced that tactics will change and the operation will now run on a monthly basis.
A force spokesman said: "The Met has refocused our tactics and are now running Sceptre operations on a monthly basis, with a different theme each time.
"To date, the team have recovered 29 knives, one electric shock baton, knuckle-dusters, ammonia spray and one firearm."
The spokesman added: "The team will be out in force during the week employing a variety of tactics which include intense weapon sweeps, intelligence-led policing operations to confiscate knives and proactive operations to target repeat knife crime offenders, as well as increasing the visibility of police officers."
The crackdown will also provide support to borough police and will involve officers from City of London Police and British Transport Police.
When the initiative launched in May saw 100 officers deployed to "knife crime hot spots" on intelligence led operations.
Acting Detective Chief Superintendent Sean Yates, silver lead for Operation Sceptre, said: "The introduction of the task force working closely with boroughs allows us to create a more co-ordinated and consistent approach to reducing knife crime.
"This type of activity is essential and has a real impact; however it will only ever be part of the solution.
"We are starting to see a mobilisation from the community against knife crime; and we need this to continue."
He added: "We need to change attitudes to carrying knives and are encouraging key people in positions of influence to drive this messaging forward.
"It is those individuals who will have the biggest impact on getting the message out there to young people that it is not acceptable to carry a knife."
Superintendent William Duffy from the City of London Police added: "Knife crime brings devastation to families and communities; we will continue to work with our colleagues from the Metropolitan Police and the British Transport Police to remove knives from our streets."
Knife bins can be found throughout London as part of the Met's effort to take knives off the streets. A map showing their locations across London is available on our website .
