NASA makes super durable, self-sharpening knives for under $ 100

Engineers at NASA have created such a durable knife that you never have to grind it.

Nothing is more annoying than when you have to "cut" the tomato because your knife is blunt. Engineers at NASA have created such a durable knife that you never have to grind it. The "KNasa Chef" knife is twice as sharp as any regular knife and retains its sharpness five times longer.

The "KNasa Chef" knife is twice as sharp as any regular knife and retains its sharpness five times longer.

The inventors believe that this is the first revolutionary step in the field of knife manufacturing over the past 200 years. This knife is made of super solid alloy developed by scientists at the California Institute of Technology (Caltech) and tested by NASA.

The blade is curved at a 25-degree angle (12.5 degrees on each side) - this number makes the knife sharper than other conventional knives, allowing users to cut more accurately. The blade also has serrated teeth that can sharpen itself when the old teeth wear away to reveal new teeth.

In conventional steel knives, the harder the knife, the more difficult it is and the blade is more prone to chipping. However, this new knife is not only harder than steel but also anti-rust and crack. This is the product of a California company called Habitat. The company has spent many years developing this type of knife and says it is twice as durable as titanium.

CEO Adam Ackerman said: "This blade is made from a patented superhard alloy, developed by Caltech and tested at NASA. It is twice as hard as titanium, and welded to the body. Steel knives using new laser welding technology This is a new achievement of the knife manufacturing industry for the past 200 years, with hardness> 70 Rockwell (unit of hardness measurement of materials), nano saw teeth When the old tooth wears off new teeth, it will show - the knife will sharpen itself ".

Nano sawtooths provide unmatched sharpness.When old teeth wear out new teeth will show - the knife will sharpen itself.

"With a blade of 25 degrees thin, if it is a normal steel knife, it will wear very quickly. However, thanks to the super hard alloy component, this knife is actually more durable than any conventional knife. The nano teeth, this knife can cut meat and hard shell bread easily ".

Habitat said the knife will be sold for nearly $ 100 and will be released in May.
