Knife crime in England and Wales hit a record high in the year to September, up by 7% on the previous 12 months.
Police-recorded offences involving a knife or sharp instrument rose to 44,771,figures released by the Office for National Statistics (ONS) on Thursdayshowed.
But the total number of homicides recorded by police fell by 6%, from 654 to617.
There was also a 20% drop in homicides where a knife or sharp instrument was used, to 221 offences, mainly driven by a decrease in London.
The figures do not include Greater Manchester Police, which records datadifferently.
Helen Ross, from the ONS Centre for Crime and Justice, said: “In the last year, there has been no change in overall levels of crime, however, this hides variations in different types of crime.
“For example, there have been continued rises in fraud, vehicle offences and robbery, and decreases in burglary and homicide.
“Although the number of offences involving a knife has continued to increase, there is a mixed picture across police forces – and overall levels of violence remain steady.
“We have also seen the number of homicides where a knife or sharp instrument was used decrease by a fifth, driven by falls in London.”
Barnardo's chief executive Javed Khan said it was "unacceptable that the knife crime crisis continues to destroy so many young lives" and reiterated warnings that this was a symptom of a "much wider, complex problem", adding: "Urgent action must be taken to break the spiral of violence.
"The Government needs to work with children's services, charities, social workers, youth workers, the criminal justice system and communities to tackle this crisis."
