The West Midlands has experienced the biggest increase in knife crime of any part of the country outside London.
The scale of the problem in the area covered by West Midlands Police was revealed by the Home Office, as it published plans to crack down on violence.
Home Secretary Amber Rudd launched a £40 million Serious Violence Strategy, which warned the increase in violent crime was linked to a rise in the sale of crack cocaine.
She said: "As a government we will never stand by while acid is thrown or knives wielded. I am clear that we must do whatever it takes to tackle this so that no parent has to bury their child."
The strategy document included a graph showing how knife crime has increased across the country. And the graphic, which does not include London, shows that the problem is growing fastest in the West Midlands.
The number of crimes involving a knife or sharp instrument has risen by more then 1,000 a year in the area covered by West Midlands Police, comparing the year to September 2014 with the year to September 2017.
It reflects a general increase in violence. A total of 52,176 crimes involving violence against a person were recorded in the 12 months to September 2017 i the area covered by West Midlands Police, which includes Birmingham, Solihull, Coventry and the Black Country.
This is an increase of 11per cent compared to the year previously.
The Government has come under fire from Labour, which says cuts in police numbers are partly to blame.
Home Office figures show the West Midlands had 8,626 police officers in 2010, and the number had fallen to 6,756 in 2017.
As recently as Sunday April 8, a woman believed to be in her 30s was in a critical condition in hospital after suffering suspected knife wounds following an incident in Walsgrave Road, Coventry.
Police were last week hunting three men after a teenager was robbed at Sutton Coldfield train station. A gang threatened to stab the 17-year-old boy if he did not hand over his valuables .
Also last week, a teenager has been charged with the stabbing of a mother who had just dropped her child off at a Black Country nursery.
West Midlands traffic cops revealed in March how they faced threats of knife violence , in a series of shocking social media posts.
The government's new strategy includes plans to:
Call on social media companies to do more to rid the web of violent gang content
Set out tough restrictions on online sales of knives following concerns that age verification checks can be sidestepped
Make it a criminal offence to possess corrosive substances in a public place
Reveal plans to consult on extending stop and search powers so police can use the tactics to seize acid from suspects carrying it without good reason
Make it illegal to possess certain weapons, including zombie knives and knuckle-dusters, in private
But Ms Rudd faced embarrassment as she insisted she had not seen an analysis prepared by her own department that says cuts to police numbers have "likely contributed" to a rise in serious violent crime.
A document obtained by the Guardian said resources dedicated to serious violence "have come under pressure and charge rates have dropped", adding: "This may have encouraged offenders."
It was "unlikely to be the factor that triggered the shift in serious violence, but may be an underlying driver that has allowed the rise to continue".
A highlighted box summarises the point: "Not the main driver but has likely contributed."
The document said that it was unlikely that "lack of deterrence" was the catalyst for the rise in serious violence and noted that "forces with the biggest falls in police numbers are not seeing the biggest rises in serious violence".
Ms Rudd told BBC Radio 4's Today programme: "I haven't seen this document.
"There are a lot of documents that go round the Home Office. We do a lot of work in this area.
"Of course violent crime is a priority. I think that you do a disservice to the communities and the families by making this a political tit-for-tat about police numbers."
