Designed by Darriel Caston of D Rocket Design, the MinimalX is an evolution of a knife originally made for SpaceX to commemorate a rocket launch. Darriel’s work caught the eye of someone in the company who commissioned him to make a custom series of knives for the crew. The MinimalX is all about fitting as much strength and durability into as small a package as possible, for a capable everyday carry you can take anywhere-even to outer space.
