"There are very few reliable sources of information regarding knife crime in the UK and as such the true scale of the problem is unknown. In order to fill this gap, the Royal Armouries Museum in Leeds has commissioned Perpetuity to undertake a review of available research on knife crime in the UK. The main objective of this research is to independently critique existing research on knives and knife crime. As part of this review, Perpetuity will investigate what data currently exists, how reliable this data is and seek to unfold any limitations of these data sets. If you have any research or information that may inform this study we would like to hear from you. For more information on this research or any other work undertaken by Perpetuity contact Michelle Duffin."
