From the heavens to your hand. The blacked out Mbombo™ isn’t just a knife; it’s a testament to the fusion of ancient inspiration and modern metallurgy—a work of art aptly named for the Kuba god of creation. But while this EDC folder’s name has primordial roots, its engineering is advanced, inspired by a commemorative design custom-made for the crew of a SpaceX launch. Known for excellent edge retention and corrosion resistance, the black titanium nitride-coated M390 blade delivers strength and sharpness with every cut, deploying at impressive speeds thanks to the smooth-opening IKBS™ ball bearing pivot. With a sleek, black titanium handle that’s lightweight and easily pocketable, the Mbombo’s unique design and capability make it a suitable EDC for any environment, from urban streets to outer space.

Powerful, precise, and pocket-sized. Inspired by a quest for spacefaring strength, the blacked out MinimalX™ delivers surgical precision in a compact package. Designed by Darriel Caston of D Rocket Design, the MinimalX™ is an evolution of a knife originally made for SpaceX to commemorate a rocket launch. This folding knife 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. Both the stainless steel handle and 12C27 blade have a brush finish and titanium nitride coating for exceptional corrosion resistance. When deployed, it’s secured by a sturdy frame lock integrated directly into the stainless steel handle. It rides low and out of sight in a front pocket thanks to the deep-carry clip, but its small size means it can easily slip into any other pocket comfortably, too.

A contemporary knife steeped in tradition. The Forebear is an everyday carry with a classic slip joint mechanism based on a pivotal, centuries-old design that remains popular to this day. Built to handle cutting tasks of all sizes, it features a two-blade design with larger and smaller Wharncliffe blades that open at opposite ends of the handle. Crafted from quality materials, the blades use 12C27 steel with a nail nick for easy opening and the handle is made of textured Ultem for extra grip. All in all, it’s a strong and lightweight folding knife with a time-honored design.

Descended from greatness. Destined for more. A nod to the iconic knives that came before it, the Ancestor is a folding knife that balances old-fashioned style with modern convenience. Made from tough D2 blade steel, the knife is ready for hard use, with improved slicing capabilities thanks to the upswept tanto profile—a shape that originated in another millennium. The liner lock and IKBS™ ball bearings ensure safe and smooth action, while the G10 handle has excellent grip and comes in a striking pattern that’s reminiscent of classic wood or gemstone. The Ancestor is an everyday carry that you’ll be reaching for today, tomorrow, and years to come.
