Leveraging the power of a patented metal alloy developed by NASA and Cal-Tech, Ultimatedge Knives claims this new survival blade is the sharpest ever crafted. The magic, if you will, is in the LIQUIDIAMOND edge that boasts the metal alloy—which is supposedly twice as strong as titanium—combined with Diamond-Like Carbon and tungsten. The edge construction allows the 9″ knife to effortlessly glide through thick rope and other hardy materials. You’re basically buying a small samurai sword. That’s enough to get us interested, but it’s far from the only reason this blade is worth the investment. The tip is so strong it can pierce, drill, and carve without fear of snapping, while a finger choil allows for better control when in use. And while it’s hard to see with the naked eye, the edge is serrated and sharpens on its own. You can read a lot more about the technology on the brand’s Kickstarter page. Then back it and get ready to slice and dice anything in your path.
