Humans have likely been making knives in some form or another for longer than we’ve had language. As such, most of the improvements to the craft have been incremental, rather than revolutionary leaps forward. Today, that’s not the case at all, as the Ultimatedge fixed-blade survival knife might just be the biggest advancement to knife-making in over a century.
You might think this particular blade doesn’t look like anything special, but appearances can be very deceiving. You see, it benefits from a Caltech-developed and NASA-tested metal alloy matrix, called LIQUIDIAMOND. That, paired with a DLC-coating and the addition of tungsten makes for a material twice as strong as titanium, earning the Ultimatedge a unique honor: it’s literally the sharpest knife ever made. It also boasts a lightweight and durable G10 handle, comes with a Kydex sheath, and can be backed on Kickstarter starting at just $129 (which is hundreds of dollars less than knives of similar quality).
