Most knives used in such attacks are from the kitchen, former Metropolitan Police Commissioner Sir Ian Blair suggested.
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.
"The common kitchen knife has remained unchanged for centuries so now we're hoping to introduce a safer, more intelligent design for the modern home," says Mr Cornock.
"This is especially true of household products which are freely available to the very young and very old, and used by people who may be clumsy, short tempered, drunk or mentally or physically unwell. Most people fit into one or more of these categories at some time in their lives."

Wie ungeeignet das Design für praktisch alles in der Küche ist sollte eigentlich jedem der schon mal gekocht hat klar sein - würde man annehmen, aber anscheinend wird das ernsthaft als gelungener Entwurf gesehen. Die Sicherheitsschere unter den Messern.
