The courts dealt with more than 19,000 knife possession cases last year - the highest number since 2011.
The Ministry of Justice said the rise has been driven most recently "by increases amongst juvenile offenders".
A record 41 per cent of adult offenders were jailed, while 11 per cent of 10-17 year olds were sent to prison, the BBC reported today.
The MoJ said almost a third of juvenile offenders received a caution.

Some 34 per cent of all sentences passed are for immediate custody, 23 per cent are community sentences and 19 per cent are suspended sentences.
A further 64 per cent of adult repeat offenders received an immediate custodial sentence.

The report comes after London Trading Standards found that children as young as 13 are able to buy knives in London shops.
It is illegal to sell knives to anyone under the age of 18.
As a result, 19 traders have been prosecuted while others received warnings and compliance advice.
