Nasa creates a £80 self-sharpening knife

There’s nothing more annoying than having to saw your way through a tomato because your knife has gone blunt.

But the days of having to sharpen your knives could soon be a thing of the past. Nasa engineers have helped to create a knife that will almost never have to sharpened.

Nasa engineers have helped to create an extra sharp knife that will almost never have to sharpened. The cutting-edge new ‘KNasa Chef Knife’ is twice as sharp as other blades and stays sharp for five times longer

KNASA CHEF KNIFE

– Made from an ultra-hard alloy that is twice as strong as titanium

– Cutting edge has a 25 degree angle (12.5 degrees each side), making it thin and precise

– Nana-serrations in the blade become self-sharpening through use as new teeth become exposed

– Knife edge is harder than any steel, yet isn’t brittle and doesn’t rust

– The knife will retail at under $100 (£82) and should be on the market in May

The cutting-edge ‘KNasa Chef Knife’ is twice as sharp as other blades and stays sharp for five times longer.

The brains behind it claim it is the first true innovation in knife making in over 200 years.

The knife is made from an ultra-hard alloy developed by scientists at the California Institute of Technology (Caltech) and has been tested by engineers at Nasa.

The cutting edge features a 25 degree angle (12.5 degrees on each side) which makes it a thinner blade than other knives, enabling a more precise cut.

The serrated blade becomes self-sharpening as new teeth are exposed through use.
