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


– 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.

Knife-obsession turns chef into master craftsman

Designer Nathaniel “Nate” Hargrove Bonner

Age • 35

What he sells • Handmade artisan chef knives, including chef, utility, paring and custom-made knives in stainless, carbon and damascus steel with handcast and figured wood handles; and knife accessories. He’s creating a new line of made-in-Maplewood Damascus steel knives.

How to buy • Visit 7328 Manchester Road, Maplewood, or

Knife-obsessed • “I’ve been a collector all my whole life. My grandfather tinkered with knives a lot, and I learned to sharpen in the Cub Scouts,” Nathaniel “Nate” Hargrove Bonner explained. He said that his grandfather used to buy him knives, very sharp knives “all the time,” but his stepmother and dad would always take them away. “I got to keep this bowie knife for a while one time. It was a big western gnarly-looking cowboy knife. I hid it in my sock drawer,” he said. But within a few months, his stepmom was putting something away and discovered it. He was 5. Ever the killjoy, she took the potentially lethal weapon out of the elementary schooler’s possession. “Yeah, she and my dad freaked out about that,” he said. “She was just livid. She talks about it to this day.” But he admits that he played hide and seek with items from his could-have-been knife collection for years after, “I’d hide them, and they’d take them. I’d hide them, and they’d take them.” But there are no hard feelings, his stepmom, Melody Noel, is his business co-founder and helps run the Maplewood shop.

Will work for knives • His chosen career paths have always included places “where I could be around knives all the time. In culinary school, I’d save money with food to buy better knives, then I was like I’m spending so much on knives, I should be making these,” he said. “I was trading up and selling them constantly to switch things out and into my collection.” Bonner is a graduate of the New England Culinary Institute but insists, “I don’t do anything frou-frou. I’m into rustic and traditional European food. I like doing a twist on the peasant version of something. I still cook with a Crock Pot at home.” As a professional chef, Bonner has worked as executive chef and instructor most recently for Viking Culinary School and Chaumette Vineyards & Winery. He was a knife skills instructor (of course) while he cultivated NHB Knifeworks business.

World’s oldest tool • “The first thing people did was pick up something to cut and scratch and fabricate with,” Bonner said. “There are natural sharp shapes formed by nature,” he said of rock shards that became prized caveman trophies. “We just figured out how to put a handle on it. And that’s the part that fascinates me because that’s the part that connects you to the knife.

Ultimate Kitchen Professional Knife Is Well Received

( — January 12, 2017) Coeur d’Alene, Idaho — Ultimate Kitchen announces that their Professional 8 Inch Chef Knife with a custom case has been well received by purchasers on Amazon.

Finding the right products for the right price has been a goal for internet marketer Ultimate Kitchen. For many years the company has been searching globally to find the best, most functional kitchen products for their customers. Starting their line with a silicone baking mat, their kitchen product line has expanded. Their best-selling wares have been their built-in soap dispensers. They have various options, with various features to satisfy their base. Features such as regular or foaming options, built-in or countertop models. Finishes include chrome, satin, brushed nickel and oil bronze. They offer kitchen faucets in matching finishes.

Released on Amazon last quarter, the Ultimate Kitchen Professional 8 Inch Chef Knife is one in a line of multiple stainless steel cooking knives the company offers. All have been well received by Amazon customers. Their latest 8 Inch Chef Knife has received the highest product rating available on Amazon, with 100% of buyers giving it a five star review.

“If you need a good sturdy knife to chop to dice to slice this is the one you want,” said Amazon buyer Ann S. in her review. “This is a really nice knife. The handle is a good grip for me and it does not feel like it’s going to slip out of my hand when I’m using it. The blade itself is very sharp, and will cut anything you want to use it with. The blade is stainless steel which is a very good to have in a knife. If you are looking to give it for a present it comes in a cute box.”

Patriot, an Amazon buyer said, “I’ve been cooking for a while and needed to move up to a more professional knife. Even though there are certainly loads of knives at a higher price, this one was a major upgrade from what I had been using. I enjoy using it and it makes cutting up meats or veggies so much easier. Also like the little storage box since I wouldn’t have space for it in my knife block.”

Ultimate Kitchen’s Professional Chef knife is listed on Amazon, for $59.99. This full-tang eight inch chef knife features a deluxe Pakka wood handle, designed for comfort and control. It is made from 8CR13 stainless steel, therefore is naturally resistant to rust and corrosion. It is also resistant to retaining food odors and stains.
