British Medical Journal: Ban Long Knives

"A team from West Middlesex University Hospital said violent crime is on the increase – and kitchen knives are used in as many as half of all stabbings.
They argued many assaults are committed impulsively, prompted by alcohol and drugs, and a kitchen knife often makes an all too available weapon. The research is published in the British Medical Journal. The researchers said there was no reason for long pointed knives to be publicly available at all."
