The information is not available in the format requested as it is not possible to separately identify the number of convictions for certain offences, for example murder, in which a knife was involved. It is only possible to provide conviction statistics for those offences which, in their definition, refer to an ‘offensive weapon’ (of which knives will be one sub-category) or ‘article with blade or point’. These are:
Armed with offensive weapon with intent to commit offence;
Possessing offensive weapon in public place;
Possessing article with blade or point in public place;
Possessing instrument with intent to commit an offence;
Possessing article with blade or point on school premises;
Possessing offensive weapon on school premises.
In 2006 (the latest year for which data are available), there were 242 such convictions.
Data are collated on the principal offence rule; so only the most serious offence with which an offender is charged is included.
