Or so says the headline of the Daily Mail video below the jump. The accompanying article hedges it a bit using “almost” and “stays sharp 5 times longer”.
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.
