Police-recorded offences involving knives or other sharp instruments increased by 22% year-on-year in England and Wales in 2017, official figures show.
Police recorded 39,598 offences involving a knife or sharp instrument in the latest year ending December 2017, a 22% increase compared with the previous year (32,468), and the highest number registered since comparable records started in 2010.
The Office for National Statistics (ONS) said: "The past three years have seen a rise in the number of recorded offences involving a knife or sharp instrument, following a general downward trend in this series since the year ending March 2011."
Offences involving firearms were also up, by 11%, to 6,604 recorded crimes.
These offences tend to be disproportionately concentrated in London and other metropolitan areas, the ONS said, but it added that the majority of police force areas saw rises in these types of violent crime.
