Zero: A Deceptively Simple Knife

Zero is a utility knife designed to look and feel as seamless as possible. It features a manual blade extension with an auto retract mechanism.

    Surprisingly Addictive

    Zero is hard to leave alone once it's in your hand. It's something about the clicks and haptic feel of the retract. On extension, the internal mechanism makes a really satisfying click due to the beefy key snapping into the locked position.

    Seamless and Screwless

    We devoted many hours and several iterations to create a design that does not use screws and does not require a tool to disassemble. Some of the internal mechanism is similar to the tricks used inside a mechanical puzzle.

    Blade Compatibility

    Zero is capable of accepting various blade types from most major manufacturers.
