In January, Office of National Statistics (ONS) figures showed that in the year to September 2017 the police recorded 37,443 offences involving a knife or sharp instrument.
This represents a sharp rise of 21 per cent increase on the previous year, and the highest number of blade attacks since records began seven years ago.
The rise in knife crime was larger in London, jumping by 38 per cent, and gang-related acid attacks are also on the rise.
Across the UK, violent crime overall surged by 20 per cent, robbery was up by 29 per cent, and sex offences surged by 23 per cent.
Take away all of the risk criminals face from a potentially armed victim and crime will rise.
It's okay though, London's mayor is taking away all of his subjects butter and steak knives. That will fix the problem.
