Yes we have a problem with knife crime , as to the stats l will check that. Your previous post implied that the UK and other European countries had worst gun crime than the US which isn't right .
Someone with a knife is unlikely to commit multiple murders like those seen all to often in the US with mass shootings too easy to perpetrate with automatic weapons.
Unfortunately kitchen knives can be used to kill or maim so the banning of knives would be impossible .
