How do 'anti-stab' knives work?

The Magazine answers...

Kitchen knives are the most common weapon used in fatal stabbings, say police. Now a new "anti-stab" knife has been developed, but how does it work?

Knife crime is hardly out of the headlines these days and it makes grim reading.

Stabbing deaths hit a record high of 322 in the UK last year, according to the government. Most knives used in such attacks are from the kitchen, former Metropolitan Police Commissioner Sir Ian Blair suggested.

The first "anti-stab" knife will soon go on sale in Britain and has been designed to work as normal in the kitchen, but be ineffective as a weapon.

Knife has unique "combination tip"
Tip has rounded edge instead of a point
Blade for cutting is underneath
Ergonomic handle reduces aggressiveness of the knife

The knife has a unique "combination tip" that reduces the risk of injury. The tip has a rounded edge instead of a point and the blade for cutting is underneath. While it can chop vegetables, the tip makes penetration more difficult. It also snags on clothing and skin, making it very unlikely to inflict a fatal wound.

Doctors have lobbied in the past for kitchen knives to be redesigned. They argue that while a redesign is not a complete solution to the complex problem of knife crime, it could help to save lives.

The New Point knife has been developed by industrial designer John Cornock, who was inspired to create the product after watching a documentary on knife crime. It has taken four years to develop.
