So, what makes this knife so special? Essentially, you're looking at a knife that is simply stronger, more durable, and more effective than competitors' knives because of the blade's unique material. According to its promotional video, the alloy in the KNASA is twice as strong as titanium, which means the edge stays five times longer than your average knife. And at $79, it's relatively cheap.
It's also one of the sharpest knives in the world. And it'll stay sharp too, thanks to a nano-serration technology that basically means it sharpens itself.
Finally, NASA has done something useful for us common folk. Well, aside from all its regular groundbreaking technological discoveries and displays of human engineering and ingenuity. This thing can cut steak. That's what's really important.
