New NASA Knife To Go For Sale In May: Does Not Need To Be Sharpened

The scientists at the California Institute of Technology (Caltech) have designed a self-sharpening knife that you will never have to replace. It has been tested by NASA engineers too. It is said to be the first true innovation in knife making in over 200 years. By May 2017, the Habitat KNasa Chef Knife (inspired by NASA's knife) will be up for sale. It is expected that the knife will be priced at £82 or about $100.

The Daily Mail reported that the new KNASA knife is extra sharp - almost twice as sharp as the normal knife blades and will stay sharp about five times longer than the normal knife too. This knife is made from an ultra-hard alloy is twice as strong as titanium which does not rust. It has a thin and precise cutting edge (with a 12.5-degree angle on each side). As the knife wears down with use, new serrations (teeth) in the blade become exposed and knife continues to be sharp.

According to the KickStarter, KNasa has used a patented laser bonding technology to fuse the blade with its stainless steel body. The company enlisted material scientists, NASA engineers, designers, manufacturing partners, and supply chain experts to create this revolutionary kitchen knife.

Usually, a steel knife is too soft and quickly becomes dull. They need to be sharpened frequently. There are also concerns that steel knives may react with food. Ceramic knives are too brittle are break easily. The new knife offers solution to both these culinary issues and makes cooking easier.

Moreover, most professional chef knives cost hundreds of dollars. They also rate in the higher 50s on the Rockwell harness scale. KNasa chef knife has a 70+ hardness reading. The company has also announced that it plans to keep the price of the new knife under 100 dollars.
