Home Secretary Sajid Javid has unveiled new measures to tackle knife crime including Asbo-style powers to slap suspects with curfews and social media bans for those aged over 12.
The orders, which must be approved by the courts, could also see suspects being made to attend awareness courses.
But they will not be subject to tagging and the Home Office is unable to say how the restrictions will be monitored.
Mr Javid said: “I have been clear that I will do everything in my power to tackle the senseless violence that is traumatising communities and claiming too many young lives.
“The police already have a range of measures they are using to keep our streets safe, but there is more we can do to help them in this battle.
“It is vital we continue to focus on improving the law enforcement response while at the same time steering young people away from criminal activity in the first place.”
The plans come as knife crime rates soar in the UK.
Possession of knives has increased by almost a third in five years, figures released earlier this month showed.
“It is vital we continue to focus on improving the law”
The Home Secretary even admitted losing sleep over the rise knife crime.
Writing in The Daily Telegraph, he said he was also worried about the safety of his own children: “When my teenage daughter goes on a night out with friends, I will often lie awake in bed until I know she is safely home.
“I’m sure this happens in homes up and down the country. My number one job as Home Secretary is to protect the public and keep people safe.
“And I will be the first to admit that I am worried by the number of young people who have tragically lost their lives to the horrors of knife crime over the last year.
“Far too many children — some who have only just become teenagers — are being maimed and murdered in their neighbourhoods, leaving communities terrorised. And when meeting the grieving families of young victims, I have witnessed first-hand the anguish and devastation that is being caused.”
Police Commissioner of the Metropolitan Police Cressida Dick blamed social media fuels the rise of violent knife crime.
She said: “There’s definitely something about the impact of social media in terms of people being able to go from slightly angry with each other to ‘fight’ very quickly.”
The plans have been sharply criticised by the Police Federation.
Chairman of the federation John Apter said the Government was “simply tinkering around the edges” and missed another opportunity to tackle knife crime.
He added: “While I cannot fault Mr Javid’s intentions I do not hold out much hope that these measures will have the dramatic impact I am sure he is hoping they will.
“How the home secretary thinks we have the officers available to monitor teenagers’ social media use or check they are at home at 10pm when we are struggling to answer 999 calls is beyond me.”
