The CIVIVI Hypersonic (C22011-2) is a sleek and high-performance folding knife designed by Gustavo Cecchini. It features a reverse tanto blade.
Unleash precision, power, and lightning-fast performance with the CIVIVI Hypersonic C22011-2—a dynamic collaboration between master designer Gustavo T. Cecchini, WE Knife Co., and CIVIVI Knives. Inspired by Gustavo’s custom originals, this production model brings aerospace-grade speed and rugged reliability to your everyday carry, making it the go-to tool for adventures, chores, and everything in between.
From the moment you cradle the Hypersonic’s angular, ergonomic handle, you’ll feel the confidence it inspires. Built to accommodate every hand size, the generous grip tapers naturally toward the blade, delivering rock-solid control whether you’re slicing rope, prepping food, or tackling outdoor tasks. The OD Green G10 inlays add just the right amount of texture for a no-slip hold, even when conditions get wet or slippery.
At the core of the Hypersonic experience is its blazing action. A caged ceramic ball bearing pivot assembly guarantees buttery-smooth deployment and near-instantaneous lockup. Flick the reverse tanto blade open and feel the satisfying “snap” as the stainless steel frame lock secures the cutting edge in place. When it’s time to stow the knife, the same precision mechanism ensures a safe, controlled close.
The 3.70″ Sandvik 14C28N blade strikes the perfect balance between toughness and edge retention. Its flat grind yields a razor-sharp profile ideal for precise cuts, while the stonewash finish masks scratches and reduces glare. A robust 0.118″ thickness adds durability for demanding tasks without weighing you down.
Weighing in at just 5.91 ounces, the Hypersonic rides discreetly in your pocket thanks to the low-profile, tip-up stainless steel clip. The streamlined silhouette slips effortlessly into everyday carry setups, ready to spring into action whenever the moment demands. Backed by Gustavo Cecchini’s visionary design and CIVIVI’s commitment to quality, the Hypersonic is more than a knife—it’s your secret weapon for tackling life’s cutting-edge challenges.

Cold Steel 92FK FGX Kerambit-fixed Blade Knife.
Was sceptical at first, being a plastic knife and all.
Now I love it! It has a purpose and is not ambiguous about it at all!
A great way to experience the Kerambit before committing to the "Real Deal"

This AKSA AK21 is an incredible replica. Initially, I struggled hard with it—every attempt to chamber a round resulted in a severe Failure to Feed (FTF). I hadn't even fired a shot yet and was ready to pack it up for a return. After discovering it just needs to be aggressively snap loaded, it feeds perfectly. Definitely recommend
Best price anywhere on the internet. Speedy delivery
Quality products and excellent turn around time.
